I have a 2004 Yukon and the radio seems like it has a mind of its own. You may get in the truck and radio comes on fine. You drive 20 minutes down the road & get out & cut power to truck. When you get back in truck radio may or may not come back on. This sequence is happening about 20% of the time, but it is annoying. I took the truck to the dealer & they supposedly re-flashed the control module, but it did not fix issue. Any suggestions would be appreciated. My wife loves this radio, so I would like to fix it if possible.
