I just installed hid's and when I started the bike all is O.K. I have a Garmin 550 with Xm. When I use the XM there is a low level hum. t does not increase or decrease with the revs or speed. What to do?
Most know Hum issues have been related to wires overlapping wire from other devices.Rocky, The hum is the through the XM part of the GPS.
