I've been having trouble with my skim module lately on my truck. I've gone through three of them in the last 4 months. The most recent one went out in two weeks. The dealership is trying to tell me that my electronics (satellite radio, and radar detector) is causing interference with the communication because i have them plugged into the upper outlet on the dash. Has anybody ran into the same problem, and had the same thing mentioned to them? Or is this even possible?

Thanks
