Finally got to Florida to and plugged in that 1650W .. It will do a GPS 3D but not a GPS W3D. it will pick up 9 satellites but not the WAAS satellite. I tried the Auto and manual option for the search, but no luck. Maybe I shouldn't worry about it ,,, the unit is with in .001 or .002 thousandth of my 1650D that i have been using for many years. And locks in steady as good as the 1650D.
your advice is greatly appreciated,
