My understanding is 1) if you get a non-GPS version you have to add Pinpoint to get the anchor to function, also 2) you cannot use the GPS off your HDS to anchor the Xi5. The Xi5 has two GPS receivers built in, which is why it is pretty accurate.

So if you buy the Xi5 without GPS, it is just a remote controlled tm.

This.
