For the TT App to work it needs a GPS signal which your version does not have. You could get an external (bluetooth) GPS receiver that is compatible with your iPad. A Google search will identify these. This would then give you standard turn by turn navigation. The additional services such as HD Traffic and TT Speed Cameras would need a cellular/3g connection.
I have purchase the new iPad 4G 64 GB and want to use my ipad for car navigation. Which app to I download and are the cost of the maps separate? Also, are the maps actually downloaded into my iPad and can I operate my car navigation in real time (direct sat. communication). - David41
You should purchase & download the TT App that contains the map that you need (e.g US & Canada). The App cost includes the cost of the map. The Map is stored on the iPad. You will be able to operate your car navigation in real time (direct sat. communication as your device has a GPS receiver).
OK - but once the maps are downloaded, do you still have to go though a cellular company and have a data account. If you need a data account then, for example, when you travel from Canada to the US, you will encounter substantial roaming charges that would make this approach uneconomically. Yes? - David41
I'm confused - some people here say you don't need a 3G model if you don't need the extras (speed cameras etc)
Will a regular WiFi iPad work with the Tom Tom App or is an external (bluetooth) GPS receiver crucial - where I'm confused is that Ibelieve all iPads have GPS and that 3G was only needed for connecting to the net etc
Not all iPads have GPS - only the cellular/3G ones. The other is WiFi only and here you will require an external GPS receiver to use the TT App (turn by turn navigation) - not additional services like HD Traffic and Traffic Cameras which will require the cellular version.
