My favorite feature of the BJ2 is the built-in GPS unit.

However, sometimes when the Google Maps program takes more than a few seconds to initialize/activate the built-in GPS, I'll fire up the "GPS Test" application to make sure I can even get a GPS Signal.

This program doesn't plot anything, store any data, etc., it simply shows you how string the GPS signals are, if any are detected.

I've read you need at least 3-4 GPS satellites to sync to your phone to accurately locate you (to whatever accuracy is available on the BJ2, probably within 10 feet or so I'm guessing?)

Be careful not to leave this running though, it'll drain your battery pretty quick.

Since this program requires the GPS unit to be on COM4, you'll need the MoDaCo activator.
