View Full Version : Passport 8500 connected to Starcom 1, buzzing sound no audio

Anyone know why the 8500 makes a buzzing sound when I plug it in to the audio input on my Starcom? GPS, Satellite Radio everything else works fine, except the Passport. If I set it to dim most of the noise goes away, but so does the audio from the GPS and Satellite Radio.

Help??? :chug:

You probably have a ground loop. Are you pulling power for the Escort off the bike? I had a similar issue with my XM radio. I added a ground loop isolator (Radio Shack) and it helped a little. Next time I have all the plastic off the bike I'm going to add a common ground for all my electronics. This should help eliminate any extra noise.

Oh yeah..what are you using to split the audio input for the GPS, Escort and the Radio?
