I bought an Alpine EX-10 Ipod controller (RF modulator) with a bluetooth hands free controller built in. It's a fantastic little unit and I played with it for a few minutes in my living room and was quite impressed. However, I've tried several RF modulators in my truck and there are so many stations in Columbus, I can't get any of the modulators to work terribly well for me. If I'm buying a new radio anyway, I'll buy one with Ipod controls. I wrapped it up and put it back in the box (it's in new or virtually new condition) after about 10 minutes of playing with it. The other reason I'm listing it for sale, my phone isn't on the "list" and I couldn't get it to communicate with my older Palm Treo phone (which was the main reason I bought it).
