I've got a JVC AVX-2 and the problem I have with it is that it jumps to radio automatically when I am playing a disk which is quite annoying especially on long motorway journeys. I've previously sorted this problem (quite a long time ago before changing my car battery!) by changing some of the settings but can't seem to remember what settings to change now! I think it might be something to do with PTY Alarm or something?
Any help would be much appreciated!
