I had the oddest thing happen to me on the way home the other day with my JGC. I've got a 13' Overland 5.7 with the Nav system. On my way home, the sound went away completely as well as the voice activation button stopped working. Also, I had a CD in the player and it wouldn't read it at all. Now, all of the other buttons, and navigation was working.
At first I tried restarting the stereo... Then I tried that 50 times as I was in traffic and had nothing better to do but get frustrated and hit the button
Second, I tried shutting down the vehicle and restarting it while at a stop light. Still
Third, I tried shutting it down, opening the door to completely kill all of the accessories and still
Lastly, I got home, sat in my parking spot, opened the door on the jeep and hit the start button 4-5 times, just cycling it through multiple start ups. Around the 5th time, the monitor flashed, the clock reset itself, and everything started working again
I have no idea what was wrong. I even called the dealership and of course I get the usual "Well, if it's working now, we probably can't figure it out" BS. Whatever, lol.
Has anyone run into a similar issue like this? I only have around 2800 miles on this thing.
