Programming The Axxess Interface And Climate Display; Final Assembly; Audio Level Adjustment - Metra Electronics 99-7388HG Installation Instructions Manual

PROGRAMMING THE AXXESS INTERFACE AND CLIMATE DISPLAY

Programming the Axxess interface:
1. For the steps below, the L.E.D. located inside the interface can only be seen while active.
The interface does not need to be opened to see the L.E.D.
2. Start the vehicle. The L.E.D. will initially turn on solid Green, then turn off for a few seconds
while it auto detects the radio installed.
3. The L.E.D. will then flash Red up to (18) times indicating which radio is connected to the
interface, and then turn off for a couple of seconds. Pay close attention to how many Red
flashes there are. This will help in troubleshooting, if need be. Refer to the L.E.D. feedback
section for more information.
4. After a couple seconds the L.E.D. will turn on solid Red while the interface auto detects the
vehicle. The radio will shut off at this point. This process should take 5 to 30 seconds.
5. Once the vehicle has been auto detected by the interface, the L.E.D. will turn on solid Green,
and the radio will come back on, indicating programming was successful.
Programming the climate display:
1. Turn the parking lights on.
2. Turn the vehicles light dimmer all the way down, then all the way up.
3. Turn the lights off.
4. Test all functions of the installation for proper operation before reassembling the dash. Refer
to the Steering Wheel Control Settings section for customizing the buttons, if so desired.
Refer also to the Audio Level Adjustment section for adjusting the amplifier gain, if need be.

FINAL ASSEMBLY

1. Secure the radio assembly to the dash using the factory screws.
2. Reassemble the dash in reverse order of disassembly to complete the installation.

AUDIO LEVEL ADJUSTMENT

1. With the vehicle and radio turned on, turn the volume up 3/4 of the way.
2. With a small flat-blade screwdriver, adjust the potentiometer clockwise to raise the audio
level; counterclockwise to lower the audio level.
3. Once at a desired level, audio level adjustment is complete.
