I have a 2008 Chrysler Aspen. When I start the vehicle, everything is fine for about 5 seconds. After 5 seconds, there is no sound but the radio seems fine. I can change the stations or switch to Sirius XM, Aux, and CD but there is no sound coming out. When I turn the car off and turn back on, it works again for 5 seconds before going out again. Does anyone know what is causing this problem and how to fix?

 

Sounds like you may need a software update. Does this happen only when using satellite radio or does it happen in all radio modes?

Below are a couple TSB that might apply to what your experiencing:

This condition may occur when the radio is in the SAT mode during power-up, the

Good luck on resolving this issue asap!

 

No the sound goes out with any feature, i.e radio, cd, and satellite and does not start again until the car is completely off and restarted. The TSB's below will not help me because I do not have a nav radio. It is just cd, satellite, and mp3.
