I use the Belkin which I bought for my GT Cruiser and it worked horrible in that car. Just per chance I tried it in the Crossfire (my son had confiscated it) and it seems to work a lot better. Must have to do with the mast antenna on the GT vs. the window antenna on the Crossfire. I think the strength of these devices is all subject to the radio stations that are around the frequencies you can tap into. In the DC area there are frequencies close to all 4 positions on the Belkin but for some reason the I-pod signal is strong in the Crossfire. I would prefer a hardwired connection but this will have to do, don't want to change my head unit right now.
