Personally, I found one at the Mall in one of those kiosks that works great. Unfortunately I paid way too much for it but have been finding them online for great prices. You can use any FM station and it also charges your Touch at the same time. Holds onto the Touch very securely and also has a USB port so you can charge other electronics as well. If you have the iPhone it also comes with a plug so you can hear your phone call through the radio speakers. I have no issues even when trying to put it on a station with a strong signal. No interference. Here is a link to a place that has a pretty good price and it looks exactly like the one I have. I paid more than twice this price because I was impatient. Definitely worth the money and they have a short goose neck or a long one depending on where your data port or cig ligther is on your vehicle.
