AmpPRO PC App (cont.)
Firmware Updates
The AmpPRO app will also allow you to update the interface with new firmware as it becomes available. Please visit
www.pac-audio.com or contact our tech support department to see if there is a firmware update for your interface.
Connect the interface to your PC and select "Firmware", then "Update Firmware". Now select "Select File". Finally, browse to the
place where you saved the file and select it. This will begin the updating process. Once finished, disconnect the interface from
the PC and resume normal operation.
Radio Reset Procedure
The Radio Reset Procedure is used to speed up the installation process when re-configuring the radio for non-amplified vehicles or
when OEM features are lost after installation. We recommend doing this procedure during the AmpPRO installation.
1. With the radio on (LED 1 red), press and hold the programming button until the LEDs are alternating flashing amber.
2. Release the programming button (you have 5 seconds before it moves to the next function)
3. The LEDs will start alternating flashing green and the radio will visibly restart.
In vehicles that do not support this reset, the LEDs will not flash amber. You will instead need to complete the "Sleep Cycle
Procedure" outlined below.
Sleep Cycle Procedure
The Sleep Cycle Procedure is used if the "Radio Reset Procedure" is unsuccessful in re-configuring a non-amplified system,
restoring lost OEM radio features or graphics, or restoring the factory system after AmpPRO removal.
1. Turn the vehicle ignition off
2. Exit the vehicle and close all doors, trunk and/or tailgate
3. Lock the vehicle with the keyfob and move the keyfob at least 25 feet away from the vehicle
4. Let it sit for 10 minutes
5. Unlock the doors, turn the igniton on and wait for the radio to boot up.
6. Repeat steps 1-5 for the second sleep cycle
