After two e-mails here is customer service reply. The concern that you described is being investigated. However, at this time, it has been determined that this is a characteristic of the radio. please stay in touch with service dept of your chrysler dealership as if any updates become available, will we notify the dealership accordingly.... Well that makes me feel better, I guess there is no problem, I'll just turn the radio on at night or get a dark tint for the windows.
