Actually - the Sony head unit that I got in my new Foz has a full featured iPod link, and can take mp3 USB sticks in the front and does intelligent searching, even properly reads idv3 tags.

It is still coming out so the empeg can go in, but I think SWMBO will get the Sony in the 'Preza (she only listens to radio and I only have one radio module...)

Still got to get time to swap them over, but luckily the Foz is a japanese import, so it has DIN slots. Yay!
