Query: Ended up returning it: stay away from it

By now I should know better. Anything that broadcasts an audio (or video signal) with less than commercial broadcast strength or using FM airwaves (this saves the GHz portion of the spectrum, which is where wireless networks and cordless phones work) is bound to meet interference in the face. That's what I encountered with the iTrip. I was dissapointed to find that, no matter how much I tweaked it, minimal movements of the iPod with the iTrip on it were met with loud noise and scratch-like sounds coming out of my speakers.After several days of trying it in my two cars (a Toyota Echo and a Passat Wagon), I gave up, repacked it and returned it for a refund. My recommendation: stay away from it. I am now looking for "wired" alternatives.
