i though t i saw a post on here about people having their head units replaced under warranty due to poor reception. can someone help me out with this? i have a Garmin portable nav system that when i put it in my 08 GP it does not receive the traffic, but when i put it in my Navigator or my buddy's car it works great. The traffic si sent via and FM signal so the cord has a receiver i built in to it and uses the factory Head Unit and antenna to get these signals. It used to work fine but lately it has died on me, and my normal FM stations are staticy and do not come in very clear most of the time. can someone give me some pointers as to what to do? thanks in advance.
