Query: Poor performer

I owned a previous version of the iTrip that I really enjoyed. I expected higher quality, volume-adjustable sound. I expected to be able to tune it to any station that my car plays.Instead, I have to crank my car radio all the way up to 90%, and can only use it in rural areas where there's not a lot of radio traffic.For whatever reason, Griffin decided not to include 87.~ range on this device - that's the only spot in my area that doesn't have traffic.I basically bought a $40 car charger.
