Query: Save Your Money

I bought this item from a major computer store, and I couldn't be more disappointed. Setup was difficult initially as it kept prompting me for the Windows XP disk (I don't have it, I have a company computer), so I got the drivers from the website and got it running. After playing around with it, I got it working on my home stereo. The sound was marginal at best. In my car, though, it was much worse. I tried many stations, and the signal was extremely weak on all stations. I have a transmitter for my XM radio, and the difference between the two is huge. The problem is not with my radio or with broadcast frequencies, it seems to me that the signal coming from the iTrip is just extremely weak and works best when the unit is literally "right on top" of the antenna (not possible in a car). Save your money.
