Anyone else having problems with their radio switching stations on them? I have the infinity radio with the GPS, etc. and every so often, the station will just change on me. I read through the instruction book and it seemed to indicate that the traffic problem notifier is what causes this. I went in and turned that off, or so I think I did. This afternoon it up and changed on me again with it being turned off. It always goes to the same station and i'm finding it quite frustrating. Anyone else suffering from this? If so, has anyone found a way to make it stop?
