I have a '05 Chrysler 300C 5.7L V8 Hemi. Had it for about 5 year now and about 2 years ago I started having issues with the stereo. Whenever I would hit about 60mph my screen would black out for a quick second then return. During the winter the screen would black out during extreme temps an even when I turned the stereo on it would only play the radio and allow me to navigate between AM/FM/CD (with a blacked out screen). Now the screen is completely blacked out and the stereo is stuck on AM frequency and I cannot alternate between other functions. Honestly very frustrating. I have tried replacing there entire system with another brand stereo, but no luck with working (even with the proper stereo connection adapters). Any suggestions????
