I've read these are pretty good, but I got a Kensington RDS transmitter and I thin it works well and charges the ipod. Scrolls track & artist name on radio display which is quite cool, and sounds reasonable IMO the same as an actual radio station, with very little hiss. We use it for trips to the highlands to visit family and finding a clear frequency is a doddle. (I find 107.9 works well around most of Glasgow) Managed to get a used one off ebay for around half the retail price.
