Infotainment/Factory Amplifier Adjustments
The RadioPRO app will also allow you to adjust the settings of the factory amplifier (Y91 / UQA Premium systems only). You
can adjust Amp Gain, Fader, Balance, Bass, Mid and Treble. When real time fade is enabled in amplified systems, it will allow
fading to be controlled directly from the aftermarket radio. Restoring factory settings on the module will default all values back to
middle.
Rear Seat Entertainment (RSE); If equipped
The factory RSE system will function independently from the aftermarket radio. The unit will power up and pass audio through the
headphones as long as the vehicle’s ignition is on. Audio from the RSE cannot be passed to the aftermarket radio when using the
GM1A-RS. If you wish to pass audio to the aftermarket radio you must use the GM1A-RT or GM1A-RST.
Testing and Verification
1. Turn the ignition on. LED 1 will illuminate red and the +12v accessory wire will turn on.
2. Turn on the radio and check chimes, volume, and balance.
Note:
Premium Bose Systems (UQA / Y91)
will not fade
from the aftermarket radio. If you want to adjust the fader you must use the RadioPRO app, available for download at
https://aampglobal.com/RadioProApp. Please see the RadioPRO app section, at the bottom of this page, for more details.
3. In vehicles equipped with Premium Bose (UQA / Y91):
If the overall volume is too low, use the adjustment dial on the side of
the interface to set it to the desired level. The best way to do this is to turn the volume on the radio to 3/4 volume, then turn the
adjustment dial on the GM1A-RS clockwise until some distortion is heard, then counter-clockwise a little.
4. Verify that all SWC buttons are functioning properly. If you are installing the GM1A-RS into a Corvette, and are experiencing erratic
SWC behavior, you may need to follow the SWC re-calibration procedure in the next section.
5. Turn off vehicle and remove key. RAP will be active and keep the radio on for 10 minutes or until any door is opened.
6. LED 1 and the radio will turn off when RAP turns off.
