Not allowing radio, GPS, or Sirius to be used. I was able to plug in my Iphone and listen through speakers, but that was it. Brought it to shop and was told not under warranty any more. (3 months past) Have seen on other sites this same issue. Was wondering if anyone else had problems. Thanks

I have seen some problem when charging system voltage was erratic due to failing alternator, or when getting too much A/C (ripple) from failing alternator diode and even with a failing battery or poor corroded ground connections that can effect any radio.
