has anyone made the FM transmitter setup actually work and not get any interference? I set mine up in my trucks with direct input into my decks but my dad (he also got Sirius the same time as me to save a few bucks) and insisted in not going with an aftermarket deck because he likes the steering wheel controls to the factory deck.... anyway, he is getting a ton of interference and I have tried about a dozen different blank FM channels. 1. How well does the Fm transmitter work for you? 2. What happens when you go on a road trip, do you have to search for a new channel all the time? 3. Which Sirius channels do you listen to the most? I'm really liking hair nation, buzz saw, hard attack, blue collar comedy, and the playboy channels.
