Mechanical installation

An installation cut-out for the car radio is provided in most vehicles. The choice of the installation location depends on safety aspects. Therefore we recommend that you actually install the car radio in this place.
The device requires a DIN installation cut-out with the dimensions 182 x 53 mm; these dimensions are standardized and most vehicle manufacturers comply with them.
Should there be no installation cut-out, please consult your car dealer about the correct place of installation for   our car radio.
Please select the place of installation carefully so that the device neither impedes the driver nor distracts them from what is happening on the road.

Use the supplied installation material to guarantee a safe installation.

Any modifications to the vehicle that become necessary due to the installation of the car radio or other components must always be carried out in such a manner that neither traffic safety nor the car stability is affected. In most cases, cutting out a piece of sheet metal will render the type approval null and void.

Since the device becomes hot during operation, the place of installation must be heat-resistant.

Make sure before drilling the attachment holes that no electric cables, brake lines, fuel tank or similar can be damaged.

When using tools to install your car’s hi-fi components, follow the manufacturer’s safety instructions.

When installing the car hi-fi system, consider the risk of accident which can arise from devices being torn away in the case of an accident. Therefore, you should secure each component in a place where it cannot be dangerous to passengers.
Before you install the device, check the depth of the installation recess. A minimum depth of 100 mm is required for installation.

**a) Installation into the radio recess

**

• Unlock the installation frame with the two unlocking keys (figure 1, item 1).
• Remove the installation frame towards the back of the device (figure 1, item 2).
• Insert the installation frame into the respective cut-out in the vehicle (fig. 2).
• Bend down some clips in the installation frame until the frame is securely fastened in the recess (fig. 3).
• When you have made all the electrical contacts (see “Electric Connection”), insert the device into the installation frame until it locks in (fig. 4).
  Keep the two unlocking keys in a safe place. You will need them for a later removal of the device.

b) Removal

• Unlock the device by inserting the two unlocking keys into the slots on the side of the device frame.
• Carefully pull the car radio out of the installation frame.
• Loosen all plug connectors on the back of the device.

c) DAB antenna
For adhesive installation, a minimum temperature of 15 °C is required. Clean the adhesive areas with a suitable cleaner (e.g. rubbing alcohol) before installation.

The antenna should not be attached in the area of metallised windscreen parts or close to heating wires.

Do not attach the antenna within the driver’s field of view. It should not interfere with the driver’s clear view of the road.

Select the place of installation with due regard to the length of the connecting cables. They should be long enough to reach the site of installation of the car radio.

The DAB antenna and connecting cables must never be installed within the release range of an air bag.

• The antenna should be mounted within the upper corner of the windscreen and A-pillar (at the top right from the driver’s perspective).

• Use the picture below to determine the mounting position.

• The black electronics box and antenna wire should be attached to the windscreen and the copper-closured ground plane to a metal part of the windscreen frame. Make sure the coating of the metal part of the windscreen frame is intact in doing so.

• Peel off the protective films and attach the antenna such that the cable outlet faces the covering of the A pillar.

• Once attached, the antenna should not be subject to any mechanical strain for 24 hours.

• The connecting cables must be guided to the car radio installation recess.

Electrical connection

Electrical connection must always be carried out by a specialist.

To avoid short-circuits and resulting damages to the device, the negative pole (ground) of the vehicle battery must be disconnected during electrical connection. Only connect the negative pole of the battery when you have completely connected the device and checked the connections.

Use only a voltmeter or a diode test lamp to check the voltage of the vehicle system leads, as regular test lamps consume excessive voltage and may thus damage the vehicle’s electronics.

When laying the cables, make sure they are not squeezed or abraded on sharp edges. Use rubber grommets for the lead-though points.

The line towards the speakers must be a bifilar cable. Insulate the bare wires at the connecting terminals.
Ensure there are no sharp edges that may damage the cables. Ensure that your speakers have a sufficiently high power rating (see “Technical data”). Ensure that all the speakers have the correct polarity, i.e. the plus and minus marks must match. The connecting cables of the speakers are usually coded: Some manufacturers mark the (+) line with an additional colour band. Others use a corrugated line for the (+) pole and a smooth one for the (-) pole. The system was designed for the operation at speaker impedances of at least 4 Ohm. Never connect speakers with a lower impedance.

In most vehicles, the cables for the electric connection and the connection of the speakers have been laid directly to the installation recess.

If this is not the case, please ensure that any cables placed later are secured by the respective on-board fuses (see vehicle operation manual)

a) Connecting the antennas

FM antenna

• Insert the plug of your car’s antenna into the FM antenna port (24) on the back of the device.
• If your vehicle has a different antenna plug, please use a suitable adapter available in specialist shops.

DAB antenna

• Insert the plug of the included DAB antenna into the DAB antenna port (20) on the back of the car radio.
• Manually tighten the union nut to secure the antenna.
• Connect the thin black wire of the DAB antenna to the antenna control output of the ISO plug (system plug A, terminal 5, blue wire, see also “Connecting the speakers and the power supply”).

b) Connecting the LINE outputs
The car radio has LINE outputs (23) for connecting a power amplifier.
The LINE outputs (23) should only be connected via suitable shielded cinch wires. Other cables may cause interferences.
Keep the connecting cables as short as possible and do not place them near other cables to avoid interferences in the cables.
To avoid distortions or mismatches that could damage the unit, the cinch connector must only be connected to devices with suitable cinch terminals.
Connect the inputs of the power amplifier to the LINE outputs (23) on the back of the device.
The red socket is a terminal for the right channel and the white socket for the left channel.
c) AUX port
You can connect an external audio device (e.g. a portable MP3 player) to the AUX port (18). The signal of the audio device is played back via the speakers.

• Connect the AUX port (18) to the audio output of the external device.

d) Connecting the speakers and the power supply
Vehicles equipped with an ISO plug can be connected directly to the ISO terminal (21), provided the same plug
configuration applies (please check in advance!). If the plug configuration differs, a commercially available vehiclespecific adapter should be used.

Contact assignment of the ISO terminal (21) can be found in the following figures. Please consult your car dealer about the respective assignment of your vehicle system plug.

7. Ignition +12 V
8. Ground

• The continuous current +12 V terminal (4) must be connected to a cable that supplies 12 V permanently when the ignition is off (terminal 30 of the vehicle electrical system). This terminal serves to save the user settings, time, etc.

• The antenna control output (5) supplies a voltage of 12 V when the device is on. This output provides power to the
  DAB antenna and a car amplifier. The thin black wire of the DAB antenna is connected to this output.

• The ignition +12 V terminal (7) must be connected to a cable that supplies 12 V only when the ignition is on (terminal 15 of the vehicle electrical system).
  Do not connect this terminal to continuous current; otherwise, the vehicle battery could get discharged when the vehicle remains parked for a longer time.

• Connect the ground connection (8) to the vehicle body.
  Adhesive techniques that evolve and the painted metal parts impair the electric conductivity. Therefore, not every metal part is a suitable earthing point.

AF > TA > PTY > VOL > BAS > TRE > BAL > FAD > LOUD > EQ > DX/LOCAL > STEREO/MONO

• AF ON/OFF
  AF ON > automatic station tracking on
  AF OFF > automatic station tracking off
  The AF function activates automatic station tracking (see “RDS as reception concept”).
  AF will be displayed. When the car radio receives no RDS station or the one with a weaker signal, the
  display flashes. When a station with a good signal is received, the symbol is displayed continuously.
  When you leave a transmission area, the device can only switch to a better station when the AF function is
  activated.

• TA ON/OFF
  TA ON >> traffic announcement switched on. The display shows “TA”.
  TA OFF >> traffic announcement switched off.
  The TA function enables the traffic announcement (see “RDS as reception concept”).
  The programme is set to mute during the traffic announcement if a different audio source is being played (e.g. USB playback).
  When the volume of the radio broadcast that is being played is very low, the volume of the traffic announcement increases automatically to a preset value.
  With the function enabled, the device only searches for radio stations with the traffic programme (display
  shows “TP”). When you leave a transmission area of the traffic information station, the device automatically searches for a new radio station with the traffic programme (display shows “TA SEEK”).

• PTY search:
  The PTY search function enables to search for stations with a pre-defined programme type (PTY) only (see “RDS
  as reception concept”).
  PTY OFF >> PTY search switched off
  PTY SPEECH >> PTY search for programmes with the speech programme type

  ---|---|---
  1| NEWS, AFFAIRS, INFO| POP M, ROCK M
  2| SPORT, EDUCATE, DRAMA| LIGHT M, EASY M
  3| CULTURE, SCIENCE, VARIED| CLASSICS, OTHER M
  4| WEATHER, FINANCE, CHILDREN| JAZZ, COUNTRY
  5| SOCIAL, RELIGION, PHONE IN| NATION M, OLDIES
  6| TRAVEL, LEISURE, DOCUMENT| FOLK M

• VOL adjusts the volume
  This function enables you to adjust the volume without having to activate the menu every time first to do so

• BAS adjusts sound in the low frequency range

• TRE adjusts sound in the high frequency range

• BAL adjusts the volume ratio between the right and left speakers

• FAD adjusts the volume ratio between the front and rear speakers

• LOUD ON/OFF
  LOUD ON >> The loudness function is enabled.
  LOUD OFF >> The loudness function is disabled. The sound is not affected.
  The human ear is less able to perceive low and high tones at low volumes. An increase in the frequency
  range at low volume (loudness correction) counters this effect, and the music sounds more natural.

• EQ – EQUALIZER
  EQ OFF >> equaliser off
  POP >> pop music preset
  ROCK >> rock music preset
  CLASSIC >> classical music preset
  JAZZ >> jazz music preset
  FLAT >> equaliser on, linear frequency response

• DX/LOCAL

• As the search progresses, display (5) shows the number of stations found.

Station selection

• Repeatedly press the buttons (1) and (9) until the desired station appears on the display (5).
• The device will switch to the selected station after a short time and it will be played.

Station buttons

• Configure the station you want to save.
• The selected station can be saved by long pressing station button 1-6 (12-17).
• You can then select a previously saved station directly by briefly pressing the respective station.
  The DAB range has six station buttons. Thus, you can assign up to 6 station buttons.

Calling up station information

• You can display various information about the station that is being played by briefly pressing the
  BND/ID3 button (11).

• To switch the display, briefly press the BND/ID3 button (11) again.

• In all cases, different information is displayed for each station.

• d) Using the FM radio
  RDS as reception concept
  The abbreviation “RDS” stands for Radio Data System, i.e. additional inaudible coded information is transmitted via
  the RDS station.
  Your car radio is a device that can evaluate these coded data that are transmitted by most radio stations.
  The following essential additional data is transmitted:

  • Programme Identification (PI)
  • Traffic Programme (TP)
  • Traffic Announcement (TA)
  • Programme Service (PS)
  • Alternative Frequencies (AF)
  • Programme Type (PTY)

Programme Identification (PI)
These data help the receiver to identify a station. It enables the radio to differentiate between areas where the same
programme is transmitted. When the reception signal gets weaker, the car radio only switches to a station with a stronger signal if it transmits the programme with identical identification.

Traffic Programme (TP)
This signal enables the receiver to detect that a station with a traffic programme is being received.

Traffic Announcement (TA)
With this signal, the receiver can detect a traffic announcement and interrupt the playback of a different audio source.

Programme Service (PS)
This information tells the receiver which station it is receiving. The station name, e.g. BAYERN 3, appears on the display of the car radio.

Alternative Frequencies (AF)
A list of alternative frequencies that send the same programme is transmitted. If the signal of the received station becomes too weak, the receiver detects from the AF signal at which frequencies it must search for a station with a stronger signal.

Programme Type (PTY)

This code gives the receiver information about the type of the transmitted programme (e.g. sports, classic, news etc.).

The listener can select his favourite programme purposefully.

A national disaster alarm can also be transmitted this way. However, not all radio stations offer the PTY service.

Therefore, when you leave the transmission area, the RDS system favourably automatically switches to a similar station that can be better received. However, it only switches when it finds a better station with the same programme.

The RDS system cannot eliminate short signal attenuations associated with the reception since this would mean that the car radio permanently switches back and forth. That would disturb the listener even more than short-term reception problems.
Another advantage of the RDS system is that the station name is displayed. The RDS station name is shown on the display of the car radio.

Button functions
BND/ID3 button (11)
Band range switching:

• Briefly push this button to select the band range of the radio module.
• There are 3 FM ranges:
  FM1 > FM2 > FM3
  Each of the three band ranges enables to save 6 stations with station buttons 1-6 (12-17).

Buttons (1) and (9)

• These buttons enable to change the reception frequency to adjust stations in radio mode.
• Briefly pressing a button starts the automatic station search.
• The search only stops at the next found station with a strong signal.
• Long pressing of the button activates the manual station search.

• This mode enables stepwise frequency adjustment with each press of the button.
  When no buttons are pressed for a longer time, the device switches to the automatic station search. AUTO will appear briefly on the display.

Station buttons 1-6 (12-17)

• If you briefly press these buttons, you can select a preset station.
• If you want to save a station you are currently listening to, just press the desired button for about three seconds.
  Each of the three FM ranges (FM1-3) has six station buttons. Thus, you can assign up to 18 station buttons.

F/PS/ button(2)

• Keep this button pushed to activate automatic storage of stations. This function enables automatic assignment of all stations with a strong signal to station buttons 1-6 (12-17).
• After this procedure, the stored stations are played for a few seconds.
• Briefly pressing this button plays all stored stations for a few seconds (same function as automatic storage of stations).
• To permanently play the selected station, briefly press the F/PS button (2) again.
• This button is also used to operate the hands-free set (further details can be found under the “Bluetooth® operation” of this manual).

e) USB/memory card operation

The device is equipped with a USB port and an SD memory card reader. MP3 files stored on these media cannot the played.

Do not connect an MP3 player operated with batteries with the USB port. The power supply of the USB port
can charge the batteries and lead to overheating and even explosion of the batteries.

USB data carriers with a memory capacity of up to 64 GB and current consumption of up to 500 mA can be

connected to the USB port. The device also supports SD cards up to 64 GB. All data carriers must be formatted in FAT 32.

• To end a phone call, press the F/PS/ button (2).

Audio streaming
Audio streaming is the Bluetooth® transmission of audio data (music) to the car radio.
Owners of an A2DP-capable mobile phone can connect it to the car radio using the pairing function as described above and send audio data.

• Make sure that both devices were connected via pairing.
• Play an audio file on your mobile phone (refer to the corresponding instruction manual).
• Press the MOD/ button (3) until the display (5) shows “BT”.
• Audio transmission is now activated.
• You can now use buttons (1), (9) and 1/ (12) to remotely control the playback of your mobile phone in the same manner as with USB and SD data carriers.

Maintenance and cleaning

• Regularly check the technical condition of the car radio, e.g. for damage to the connecting cables or the housing.
• If you suspect that safe operation is no longer possible, stop using the product immediately and prevent unauthorized use. Disconnect the vehicle electrical system!

a) Changing the fuse

• If you need to replace the fuse, only use fuses of the specified type and rated current (see “Technical data” for details).

Do not repair fuses or bridge the fuse holder.

• When the power supply has been disconnected (disconnect the ISO plug!), carefully remove the fuse (22) from the fuse holder near the ISO terminal (21).
• Replace it by a fuse of the same type.
• After that, you can reconnect the car radio to the vehicle electrical system and turn it on.
• If the fuse blows again, have the device repaired in a specialist workshop.

b) Cleaning

• Clean the exterior of the device only with a soft, dry cloth or brush.

Never use aggressive detergents, rubbing alcohol or other chemical solutions, as these may damage the housing or prevent the product from proper functioning.

Troubleshooting

Your car radio is a product that has been designed according to the state of the art and is reliable in operation. Should
you face any problems and malfunctions, please refer to the following explanations for troubleshooting.

No playback, display and backlight are off

• The vehicle fuse is defective. Look up the respective fuse in the operation manual of your vehicle. Check the fuse.
• The fuse of the device is defective. Remove the device and check the fuse (22).
• The positive line/ground line is loose. Remove the device and check the connection of cables.

Playback only through one speaker

• The balance control is wrongly adjusted. Adjust the balance control as described.
• The speaker connection has come loose. Remove the device and/or speakers and check the connections.

Playback only through the front or rear speakers

• The fader control is wrongly adjusted. Adjust the fader control.
• The speaker connection has come loose. Remove the device and/or speakers and check the connections.

The device is muted in DAB mode

• Unlike normal radio operation, where interfering noise is caused by reception interferences, the DAB playback is muted when reception is poor. This is often explained by underdeveloped communication infrastructure, especially in rural areas. This is by no means a problem with your device.
• The DAB antenna was not properly installed, for example, too close to the vehicle’s sheet metal parts or behind a metallised windscreen part. If a proper installation of the DAB antenna is not possible, use an external DAB antenna.
• The DAB antenna is not properly connected to/detached from the device or not connected to the antenna control output. Remove the device and check the connections.

No stations are received by the FM radio

• The antenna is not pulled out completely. Pull the antenna out to its full length.
• The antenna connection has come loose. Remove the device and check the connection.
• The antenna is defective. Check the connection, grounding and antenna itself.

Faulty radio, USB or SD memory card

• Interferences reach the device via the positive line. Install an additional interference suppression coil into the positive line.

• If necessary, equip your vehicle with spark-plug suppressor sockets, distributor arms etc. to suppress interferences.

• Bad ground connection. Check the ground connection; use a different ground connection if necessary.
  When you press a station button, you only hear a hissing

• No station has been programmed. Programme the stations as described above.

• The continuous positive line is not connected or has come loose. Connect or check the continuous positive line as instructed or check whether the cable is correctly connected. Check the fuse.

The device does not respond to button presses and displays unintelligible characters

• Press the RESET button (4) to reset the device to factory defaults.
