Funny you mention this 
My other hobby is building a carpc and someone has done LIVE tracking of his car when he's driving around and it uses google maps for you to view were he is right now or replay a log of where he went.
YIKES! You don't want that information falling into your wife's hands!!
It's to keep track with where your wife is going

lol
im 21 so there is no wife

That's definitely some sweet stuff - EXACTLY what I was looking for! Hey, btw, someone was looking for some GPS turn-by-turn software, mebbe cross-post or link to this post and direct 'em to this. That mp3car forum is pretty sweet, I was looking at that software for a juke for a while, but it isn't wife-friendly, so it got the axe
Well you can go buy D3 Destinator 3 altho you can download it off the net.
D3 is a pocket pc gps software and they released a pc sdk which alot of us have used and created a frontend to get the gps software useable (it wasn't useable one bit with the sdk) and after we did this they decided to charge $50 for a Dll you need then another amount of money for the SDK which pissed us off alot.
We did all this hard work to make there software work on the pc now they start charging us for all this ---steaming pile of meadow muffin--- then we have to pay $400 or so for the maps.
Look on edonkey or something like that you can find the maps (which you can get for free by destinator ask them for a free trial) then just download the free frontend etc.
you have to read the mp3car.com forums to work out what i mean.
