In Chicago, the GPS NEVER works (and yes I went by the window dozens of times). In the surrounding suburbs, it worked once about 30 miles north of Chicago, so I know it's not broken, unfortunately. TeleNav, the company that sells the GPS mapping service for Nextel phones, will charge you by the kilobyte, which is very mysterious, but comes out to about twenty-bucks a month, in addition to a "total connect" service that Nextel will need to add (for GPS to function), for another ten-bucks monthly. The kicker is when you figure out that your GPS hardly works at all, and you have already signed up for a year's Telenav service, TELENAV WON'T REFUND YOU A SINGLE DIME. "Too bad for you" it didn't work in YOUR area. The Nextel tech that I spoke to (in cancelling "total connect") said TeleNav told them that they should not gaurantee TeleNav to ever function. "There are not enough satelllites at this time". What a bunch of fargin iceholes.
