2007 Jeep Wrangler Manual Transmission: The radio turns off and then back on (shorts out?) when the engine is going really slowly. For instance, when creeping up to a stop light in second gear vice first. Why is this happening? How can I prevent the radio from continuing to do this. In the past I had a Hyundai Elantra, Ford Escort, and a Dodge Colt, all had a manual transmission and none had issues with the radio shorting out. ---
