iPad is becoming a more popular car accessory day by day as it is used for various reasons while driving.

However, manufacturers are mulling to come out with tablet-like interfaces for cars. For instance, the Tesla Model S will come fitted with a large touchscreen device at the center of its dashboard

The most common use of an iPad in the car is the Google Maps application. In order to initiate this application, the user will require buying one of the iPads with 3G and GPS and give AT&T $15-$30/month.

Though the maps application works just like the iPhone; however it is bigger and faster along with a terrain option. A compass further makes navigation and the higher definition street view that much more functional.

It has been speculated that even GPS software makers like Tom Tom and Garmin are considering making special versions of their current iPhone apps for the iPad, otherwise, you can get by with the iPhone formatted versions.
