I use 3 programs and they all find the built in GPS receiver just fine, which is on Com port 4.
TomTom 6 is great. Mapopolis works, too, and my Maritime program, Ozi Explorer works fine, too. TomTom in my opinion is way more useful than TeleNav, and doesn't require 10 bucks a month. Tom Tom also cover Canada and Hawaii where I don't think TeleNav does. All in all, Tilt does fine with its built in GPS The screen is not as robust as my Axim, but way better than a Palm. One of the nicest things about the Tilt is that at night, the display shows, but not an annoying keypad that is brightly lit up (like the Palm) which rendered it nearly useless at night. Built in GPS is a great feature.
