We put a Garmin 7012 at the
helm last
winter. I had fears about how well the touch screen would
work "in weather", etc. I used the thing all this season without a hitch. Mine is mounted at the helm, on the
pedestal, and is not protected (other than the protection from it's mounting 'pod'). I absolutely loved it. All my cruising was mid coast
Maine, but
weather was a bit of everything...the Garmin never gave me any cause for 'buyers remorse'. My reaction was more 'that is the best
money I've spontaneous on the
boat for a long time". Good luck. I think you'll love it.
