Just an update, got an RA# from Garmin on 5/23, waited until 6/1 to ship in the defective unit (while on vacation), they received and sent out a new unit on 6/6, at the house when we got back from vacation yesterday. I would say they didn't even attempt a repair, just replaced, which is fine with me. Need to update the software, be on the water tomorrow....

They have been pretty easy to deal with, although it can be time consuming to reach somebody or get a response....
