Over at MoDaCo.com there’s some excellent first-hand reviews of top navigational software ALK CoPilot for Smartphones here and TomTom here. Both of them are excellent and it’s sometimes easy to forget just how powerful your Microsoft Smartphone is!
To get the most out of either of these you’ll need a GPS (Global Positioning System) receiver, which then connects to your handset over Bluetooth. Everything else is then up to you.
