Hey guys. Quick question. Is there any way to keep the radio on after the engine is off? Pushing the power button only lets us use it for 15 minutes before powering off. Trying to keep the radio on at a drive in...

 

Probably have to turn the key on and off every 15 mins.

 

Bumping this up. I recently was at the drive in movies to run into the same problems.
Wondering if there was a fix for this?
- any way to use the Gap IID?
- any way to use the Radio Diagnostics (holding the valet button for 10s)?

Cheers
