PRIOR TO INSTALLATION

Read the manual prior to installation. Technical knowledge is necessary for installation. The place of installation must be free of moisture and away from heat sources. Please ensure that the correct tools are used during the installation to avoid damage to the vehicle or product. Aerpro can not be held responsible for the installation of this product.

INSTALLATION GUIDE

Before installing the interface, the factory stereo must be removed and disconnected. To do this, please consult the vehicle owner’s manual/handbook or contact a fitting professional.

A stereo connection (patch) lead is also required for the installation of this interface (supplied separately). Please ensure that you have the correct lead before proceeding. For universal patch leads, prepare the wiring loops in accordance with the instruction manual supplied with the product before installation.

1. Connect the 12 Pin connector from the stereo connection (patch) lead to the interface box.

2. Connect the opposite end of the stereo connection (patch) lead to the steering wheel control input on the back of the aftermarket stereo.
   NOTE: This may be a 3.5mm jack connector or a wired input depending on the brand of aftermarket stereo being fitted. Please consult the aftermarket stereo installation manual for further information on where to make the connection
   ! IMPORTANT: THIS STEP MUST BE COMPLETED BEFORE CONNECTING POWER TO THE INTERFACE. FAILURE TO DO SO MAY RESULT IN A LACK OF FUNCTIONALITY AND THE NEED TO REINSTALL THE ! PRODUCT.

3. Connect the 20 Pin connector from the supplied wiring loom to the interface box.

4. Connect the power/speaker ISO connector to the power/speaker ISO connector at the rear of the aftermarket stereo.
   NOTE: For aftermarket stereos which do not have an ISO connector, please see “Wiring Key” on Pg.2 for information on which wires to connect. Some interfaces may also have additional ‘flying’ wires which can be connected to the vehicle to support various features ie. parking brake trigger, reverse gear and speed pulse. Details of these can be found under ‘Additional Connections’.

5. Connect the additional wiring, AUX connectors & Yellow RCA connection to the aftermarket stereo’s wiring harness where required.

6. Connect the vehicle specific power connectors on the supplied harness to the OEM connector from the vehicle.

7. Test stereo and steering wheel control functionality for correct operation before reassembling the dashboard. If the steering wheel control functions are unresponsive, please uninstall the interface and wiring and reinstall carefully in accordance with the above steps.

360 CAMERA FUNCTIONALITY

Access of the 360 Camera:

When in Park – a short press of the 360 View Button (10.) will showcase the ‘dynamic 360 view’ (Figure 1). In this view, utilise the button presets to alter the various viewing angles*. Another short press of the 360 View Button (10.) will exit to the main menu.

When in reverse – upon engaging reverse gear, the ‘rear view & panoramic view” will populate on the display (Figure 2).
A short press of the 360 View Button (10.) will switch this view to ‘rear view’ (Figure 3). Disengagement of the reverse gear will exit the 360 camera mode.

When in Drive: Shifting from Reverse to Drive, the camera will switch to ‘front & panoramic view’ (Figure 4). A short press of the 360 View Button (10.) will switch the display to the ‘front left / front right view’ (Figure 5).
A following short press of the 360 View Button will exit to the main menu.

Functionality of the camera is dependent on access to ‘re-assigned buttons’. This is achievable after holding Mode for approx 8 seconds. Layout of the menu systems will differ dependent on left & right hand vehicles

360 Camera Button Settings:

Long press the Mode button (9.) for more than 8 seconds will ‘re-assign’ the steering wheel controls, this meaning you can utilise the controls for various functions whilst “Panoramic View” is enabled. Herein, you are able to toggle the look of various features such as the colour/layout of parking lines & 360 layout.

‘AUTO’ Functionality:

In addition to screen switching by operating the camera switch (10.), automatic display mode is available (see figure 4/5). In this mode, the screen is switched automatically in response to vehicle speed. The monitor will automatically display images in the following situation: 1) When the shift lever is shifted to “N” or “D” position. 2) When the vehicle speed is reduced to approximately 10mph (18km/h).

If no operation is performed after roughly 15-20 secs, the camera mode will close itself.

Language settings:

The language is completely controlled by the original vehicle system. If a desired language is needed, this needs to be done prior to installation of the new head unit as this interface does not support language setting functionality. The interface will default the language to English if not already set.
