more than likely, you would have to send in the unit itself to get it hacked... thats what i've been hearing for quite some time.
I got into the DIAGNOSTIC screen...some neat stuff like YAW rate and tracks how many satelite your car is talking to. other things like, detailed info on ur nav unit, screen(color), touch screen setup and functionality...
press MENU,SETUP,CANCEL at the same time and it shoudl get u into the diagnostic page(i stole this from TSX website trying to change the welcome message but someone already said it didn't work so I didn't even bother. It just wont show "LOADING SOME FILE" like the older units.)
EDIT PIX...took it with my phone
