There's something strange going on with the CD player in my 3 series. When playing CD's I find that if I turn off the car and come back to it after a prolonged period of time say 30min+ the CD player returns to the start of the last track played as opposed to playing it from where I left it. I noticed this when I did a number of short journey's last week and realised I was stuck on the same track whenever I got back to the car! It doesnt happen if you leave the car for short periods of time, which is weird. It happens with all CD types. Can anyone explain what's going on here and whether there's a fix? Cheers.
