I have added a GPS and Satellite radio to my 2002 Goldwing Trike, get engine noise, have tried the ground fault isolation kit to no avail, noise only is present when engine is running, rpm effects the frequency. What can I do to rectify this problem? also got any suggestions for sticking handlebar grip switches? Cruse and Mute buttons stick in....:o
Also was wondering if the final gear on this Honda is considered Overdrive. My final drive 5th gear, has a symbole like a lazy 8 or a square infinity sign.... have been looking for the acutal gear ratos but can't find, think I saw something like that when I was purchasing... thanks..:rolleyes:

I had the same problem on my 2003, I ended up putting an isolation transfermer on the audio output of the GPS (and the Aux input plug) and it removed all the noise. Purchased the transformer from FRY's for $11..
