Good Morning:  I have a 2009 34 Sundance.  It has a GPS, Garmin 2006C.  Was working fine but now says "no antenna."  I communicated with Garmin and they said it's not a software problem.  Does anyone know how I can test the antenna.  It's mounted on the top of the radar bridge.  Thanks.

I recently had this issue with my recently purchased boat with perfectly working GPS at time of sale. previous Owner told me it needed to be rebooted. Instructions were to detach the power wire under the console for 10 secs with a clear view of the sky and reattach. Haven't tried it yet
