When I picked up my new '14 K1600GT I moved my Navigator V from the R1200RT to the GT. However it fails to communicate with the bike's system; no power up nor any indication the bike's system sees it. My dealer concluded it was a problem with my Garmin unit and gave me a loaner until it gets resolved. Over the next few days - he tried my failing nav unit in three other bikes - and it worked fine in all three. Trying in my GT; no joy. Meanwhile, my loaner continues to work fine. Any ideas what this might be?
