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. Restoring factory settings on the module will default all values back to
default.
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-R. If you wish to pass audio to the aftermarket radio you must use the GM1A-RT or GM1A-RST.

SWC Re-calibration Procedure (Corvette Only)
Please Note: This is only necessary if after installation, the SWC are acting erratic or
unresponsive in the Corvette.
1. Turn the key to the ignition position.
2. Press and hold the programming button until LED 1 turns
amber
and you hear two chimes.
When this happens, release the programming button.
3. Within 7 seconds, press and hold the button that is to be learned on the steering wheel. The
LED will turn off when the button is pressed and begin blinking when the value has been
learned. Once the LED begins blinking, release the button.
4. Repeat step 3 for each additional function on the steering wheel.
5. If you come to a button in the list that your vehicle does not have, skip it by pressing the
programming button on the interface. Any buttons not learned during this process will not
function.
6.
Once programming is completed, the LED will flash indicating end of programming.
7. Test the interface for proper functionality. Whenever a SWC is pressed LED 1 on the interface
should blink green. If any function does not work, repeat the programming steps.
1. Turn the ignition on. LED 1 will illuminate red and the +12v accessory output will turn on.
2. Turn on the radio and check chimes, volume, and balance.
Note:
Premium Bose Systems (Y91 / UQA)
will not fade
from the aftermarket radio. If you want to adjust the fader you must use the RadioPRO app
,
available for download at
http://aampglobal.com/RadioProApp. Please see the RadioPRO app section on the next page for more details.
3. In vehicles equipped with Premium Bose (Y91 / UQA):
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-R clockwise until some distortion is heard, then counter-clockwise a little.
4. Chime Volume:
If the chime volume is too low, adjust it using either the procedure outlined in the previous section, or by using
the RadioPRO app. Please see the RadioPRO app section on the next page for more details.
5. If an SWI interface was also installed, verify that all SWC buttons are functioning properly. If you are installing the GM1A-R into
a Corvette, and are experiencing erratic SWC behavior, you may need to follow the SWC re-calibration procedure in the next
section.
6. Turn off vehicle and remove key. RAP will keep the accessory output on for 10 minutes or until any door is opened.
7. LED 1 and the accessory output will turn off when RAP turns off.
