Garmin 660 and Autocom
Just installed the Zumo 660 and Autocom on the new 09 RT. The Autocon is connected to the Audio out pigtail from the 660 Motorcycle mount. Unfortunately the GPS volume (set at 100%) is attenuated so much that it is virtually unhearable through the headset.
The hookup is the same as the previous Garmin 2610 and Autocom on a previous bike. With the 2610, volume was fine.
Any ideas as to how to improve the volume?
