Does anyone know what the difference is between the Zumo 660 from Garmin and the one from BRP. You can buy one from Garmin for $650.00 and the one from BRP is $1100.00. Is the mount and wiring harness for the 660 in the BRP kit different from the mount and harness you get with Garmin kit. I already have the chrome mount and wire kit that came with it. The wire kit that came with the chrome mount is just a short wire plug with a radio antenna connection.
