Wiring and Connections

Water Tight Plug Face Shown (Wires to Connect Exit Rear)

Note: See wiring chart on next page for connection tips, wire colors and functions.

• We recommend wire-to-wire connections such as power, ground and speaker wiring are soldered and protected with either heat shrink tubing or high quality electrical tape.
• The main (yellow) power wire should be connected to a source with at least 10 amps of additional current capability to support the unit.

Preamp Level Audio Connections

• Front and rear RCA preamp outputs are labeled as such. These are intended to be connected to external amplifiers, not included.

Rear Mounting Instructions

• Check for appropriate mounting depth and mechanical or electrical obstacles behind the mounting panel BEFORE any cutting. Including the “U”-shaped aluminum mounting bracket, at least 4” (100mm) depth is required.
• Using a 3″ hole saw or air saw, cut a 3” (76.2mm) diameter hole in the mounting panel. Use a file or sandpaper to smooth out any rough edges after the cut is complete.
• Thread the two supplied bolts into the back of the multimedia controller using a 9/32” nut driver or deep socket. The threaded holes are located just above the wiring harness in the heatsink.
• Thread the two supplied bolts into the back of the multimedia controller using a 9/32” nut driver or deep socket. The threaded holes are located just above the wiring harness in the heatsink.
• Thread two of the supplied 9/32” mounting nuts upside down on the bolts. The flat surface of the nut will sit flush with the inside of the mounting bracket to allow spacing (if needed).
• Insert the source unit through the mounting hole opening. Be sure to allow enough depth for wiring to be securely tied up once the installation is complete.
• Attach the aluminum mounting bracket to gauge the sizing and that it will fit over the supplied threaded bolts. If necessary, use pliers to break away the marked sections until the bracket fits snugly against the mounting panel. Be sure the bracket clears the wiring on the back of the unit without rubbing or heavily bending the wires.
• Attach the remaining supplied 9/32” mounting nuts on the threaded bolts to secure the mounting bracket.

Front Mounting Instructions

• Check for appropriate mounting depth and mechanical or electrical obstacles behind the mounting panel BEFORE any cutting. At least 3.75” (95.25mm) depth is required.
• Using a 3” hole saw or air saw, cut a 3″ (76.2mm) diameter hole in the mounting panel. Use a file or sandpaper to smooth out any rough edges after the cut is complete.
• Remove the snap-in covers on the front panel hiding the mounting holes. Use a small flat head screw driver in the two small indents on each cover to gently pry open.
• Insert the source unit through the mounting hole opening. Be sure to allow enough depth for wiring to be securely tied up once the installation is complete. Ensure the source unit is level.
• Mark four (4) holes using an awl, straight pick tool or 1/16″ (1.5mm) drill bit to make the markings. DO NOT DRILL THROUGH WITH THE SOURCE UNIT IN PLACE.
• Remove the source unit and gently drill the four (4) marked locations for mounting holes using a drill with a 1/16″ (1.5mm) drill bit.
• Re-insert the source unit in the opening. Gently install the four supplied screws in each of the mounting holes with a handheld screwdriver. Do not use drills or battery-powered screw guns for this step.
• Replace the snap-in covers on the source unit’s front panel.

Bluetooth Pairing

The multimedia controller supports Bluetooth A2DP for wireless music streaming from a mobile device, such as a smartphone or streaming music source component. The unit does not support the HF (Hands Free) or PBAP (Phone Book Access for Contacts) profiles. No calling features are available, only Bluetooth music streaming.

Pairing a Bluetooth device:

BT Pair Screen

• Ensure the multimedia controller is on and Bluetooth is the selected source. The screen will show “BT Disconnected!”
• Ensure the Bluetooth functionality on the mobile device is enabled and supports A2DP audio streaming.
• Scan for GMR-5 in the Bluetooth list on the mobile device.
• Select GMR-5 and the connection will then be made automatically.
• A “BLUETOOTH Loading” screen will appear briefly as the mobile device’s song info and album art are transferred to the multimedia source unit.

Bluetooth Pairing & Operation

If a PIN Code is Required:

Some Bluetooth devices require inputting a pass code for connection. Please input code “0000” and the connection will be made automatically.

Automatically Connecting:

Once the multimedia controller has made a connection with the Bluetooth mobile device for the first time, the unit can then connect to the Bluetooth mobile device automatically within a valid range.

Manually Disconnecting:

• To disconnect temporarily, for example to take a phone call, press and hold the 1/ button for 3 seconds and the mobile device will disconnect. If no phone call is in progress, it will automatically reconnect to the unit in about 15 seconds.
• To disconnect and allow another user to connect, use the mobile device to forget the “GMR-5” connection entirely.

Once a Bluetooth device is paired and recognized:

• Be sure the multimedia controller has the Bluetooth source selected. The multimedia controller should automatically begin playing where the mobile device last left off of the music player’s song or playlist.
• If the unit does not automatically begin playing, press the center button to play the Bluetooth source. The play symbol will display when music is playing.The time elapsed in the song play is also displayed on the screen.
