This makes sense, and points out another advantage of the N800. If you buy a separate GPS unit, you put it where reception looks best, and keep the N800 where it's most convenient for you. When I was on a cruise ship off Mexico, I put my GPS unit right up against the window glass, and I could check the position (and speed) of the ship from my bed. Try that with an N810.

Btw, my GPS add-on cost about $60.
