Ever since purchasing my 2007 Chrysler sebring, the fm or am radio won't work...it's just static on every station...however, when we were driving up into d.c. the stations were coming in clearer. is it just something with the signal? or another idea we had was that the xm radio might still be connected, causing it not to work. if you have any ideas on how to get it to work, please leave an answer. thanks
