A free country-specific TomTom Navigator 6 GPS package is available to anyone who picks up a Treo 680, 750 or 750v smartphone before 30th June 2007. The package includes a plug & go expansion card for the UK, Bluetooth GPS receiver, vehicle device cradle and power adapter. All that adds up to around £155 of extras.
As well as regular directions, Navigator 6 can also be used to navigate to contacts in your address book, with spoken and visual instructions and a choice of 2D and 3D maps, along with the usual points of interest. And it integrates with the handset, allowing you to easily toggle between GPS and phone.
