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,
