thats odd i never have any trouble with itunes on windows. I think it even worked the time the rest of the computer was locked up. All my sterios are aftermarket. well one came out of an audi but its a blauplunkt and sort of aftermarket. cant seem to keep my cds unscratched but i do burn them when iv got enough songs piled up. I got a cheapo retractable port wire from ebay for 5$ well see how it goes
Ill be happy if it works on atleast one of my vehicles. There all kinda setup a little different
