I own a 2011 CVO screaming Eagle Ultra Classic. When I plug the aux. cord into the the Road Tech Zumo 660 to listen to the music occasionally the volume will shut down and the Int will start working. The int com is shut off at the radio controls. The volume shut down time varies. When this happens if you adjust the volume controls a message on the radio reads Nav,Phone Volume. The Bluetooth on the Zumo is off and there are no headsets being used. Anyone know what is causing this? Anyone know how to stop the volume from shutting down.

 

Call Iron Cross Audio.

The navigation interface module is what is wrong. Fixed.
