I just purchased a Uniden pc68ltw cb w/ wilson antennas for my sprinter, and had it installed at a cb shop. Works great until I start my van. Then I get interference, rfi, they say. The guy more or less told me to go to the manufacturer to find out what could be causing it. Has anybody succesfull installed a Cb in a sprinter? Does anyone know of a fix for me? The Cb guy is tops in our area and knew of nothing more he could do, Please help!! I spend alot of time on the road and really want the Cb.
