I just got an iPod FM Transmitter for my week long visit to Anaheim this next week and it's a tad buggy. I was trying it out in my car and there is a bunch of static. Depending on where I have it in the car, the signal is stronger or weaker. The one that I ended up getting is a Belkin Tunecast. It might do ok for NAMM (rental car), but it's going to be returned for a better model when I get back. Any suggestions/tricks on getting a better signal? What are the best model available?
