Found these on eBay, if anyone is thinking of adding USB or aux connections to their car.
Looks like they run through USB as standard but a little work with an aux cable and a soldering iron will modify them to run only off the 3.5 socket and save having to buy 3.5 sockets and drill and fit them themselves.

[color=#0000ff][size=5][font=comic sans ms,cursive]If you have one of the Sony units with CD MP3 playback, I would prefer to make up an MP3 CD with 10+ albums on it and also have the music title displayed on the radio, + Steering wheel control of tracks, rather than a usb stick with no display, but I do admit you can get a lot more music on the stick or an ipod, it is nice to have the choice.[/font][/size][/color]
