Feed back into helmet with GPS installed when key CB mike

[stfennema]

I have a 2014 RT-S and have both CB and GPS when the gps is installed every time I key the mike there is screech through the helmet speakers. When I take the gps out of the stand noise goes away what needs to be done to fix the problem.

Is the helmet Bluetooth? If so, many GPS models have Bluetooth built in as well. Try disabling it on the GPS. Just a shot in the dark without more details.

No Bluetooth. When I first start out I only have sound in right speaker after a 20 min pop sound and have music in both speakers then have screech in both speakers when I key mike.

Sounds like the squeal I have been having when trying to transmit on the OEM CB when both passenger and rider helmets are connected to the system/bike. I am using J&M headsets. After the technician grounded the CB mounting plate to the bike, there was no squeal with a test with using two BRP headsets. If only one J&M headset is connected, I can transmit and receive without problem. My bike is a 2014 RT-S.

Sounds like there is a "wiring" difference in the BRP and J&M cable that plugs into the bike.
Do you have a wiring diagram fro the J&M?

Try this (if you have not yet)
Take the passenger "cable only" and plug it, while wearing your helmet - do you get the feedback?
Take the passenger headset only, plug in to the front and then the rear - do you get the feedback?
If no to both of the above it's incompatible wiring. Given that BOTH BRP headsets work.

Manufacturer or Headset?
