I think the Dension option may be your best bet. I had an iTrip for a while that worked pretty well driving from Chippenham to London, and down to Bristol, on one frequency, but going down to Bath needed a change, and then BBC Wales added a station just across the Bristol Channel that swamped the frequency I used to be able to use from around Marshfield on the A420, and I just got so pi55ed off having to keep changing frequency that I gave up and bought an Alpine head-unit that allows me to control the Pod and shows cover art on it's screen as well via USB in the back. Great thing is I can connect my iPhone and get spoken instructions when using my Copilot satnav through the stereo while playing music from it, which has made life easier.
