Do they have cell phones with GPS driving instruction devices?
I know cell phones have GPS tracking devices, but can any work as a GPS for giving people directions when they are driving? If not, why not? It doesn't seem like it would be too difficult to design.

yes a lot of the new phone have gps direction devices..i didnt know this i bought one for my car and then my friend was using her cell phone..of course you have to buy the service for it but its worth it so helpful
I have 2 that have that…Blackberry Curve and T-Mobile Dash. Now, if I only went somewhere….
