So far today, got the car out to fit my BMW wide-screen head unit, only to take it back out again as it is clearly a dud unit I have got
described as good working order off Ebay it clearly isn't, when I first plugged it in there was an intermittent 'whirr' coming from inside it, when I opened the door to get access to the cassette deck it then doesn't want to close, unless I unplugged it and reconnected. As I know these units are plug and play this strikes me as wrong for a start?
Bit of further investigation revealed a rattle inside, and a little white thing fell out. Looking inside the cassette deck and it's all bent inside with screwdriver marks on it and one of the drive wheels is missing and the other one intermittently spins, so this is what the noise is.
I'm going to email the seller and I want a refund on it.
