Query: Not the greatest design especially for urban use

I have had this product for approximately two weeks and have used it in both an urban environment and also in long distance travel and as far as I am concerned it is a dud. If you happen to be lucky enough to find a station where there is no interference from another signal, the itrip does indeed work. I have encountered this for at most a half an hour on a three hour journey. What generlly happens is that other stations will interfere with the station that you are listening on as you are driving. The sound quality decreases and then becomes unlistenable. In and around Boston where I am from, I have yet to find a good station. It would be great if Griffin would put up a list of channels in various regions that are good for broadcasting on. I still have hope that I can find a station to listen on without interference, but my hopes are diminishing.
