Radio/HMI settings

What radio/HMI settings can be adjusted?

There are dozens of individual settings and parameters that can be adjusted in the radio and HMI (Human Machine Interface) modules. The following is an abbreviated list of the most popular/commonly adjusted parameters to give a preview. In reality there are TONS more features that can be adjusted!

Please note that there might be minor differences in tune setting descriptions/limitations/capabilities depending on year/model of vehicles due to operating system software changes that GM has made over the years.

You do NOT have to have any licenses purchased to view all of the available tune settings in your web profile; you are free to explore, however the AutoSync will only download/install tunes into your vehicle after you have purchased a license.

 

  • Disable "liability nag screen"
  • Adjust RAP (retained accessory power) radio timeout delay (from the factory, if the ignition is turned off and all doors remain closed, the radio will turn off after 10 minutes; you can adjust this time)
  • Adjust vehicle-off manual radio power timeout. If the vehicle is off, pressing the volume knob will turn on the radio to allow you to listen to music with the vehicle off, however the radio will automatically turn off/disable itself after 10 minutes. With custom radio programming you can adjust this timeout.
