In the States, Garmin has announced Garmin Mobile PC, a navigation package that turns laptops into "powerful" navigators.

"Garmin Mobile PC gives travelers an easy and inexpensive way to get more from a device they already own – their laptop", said Dan Bartel, Garmin’s vice president of worldwide sales.

"Plus, it offers many of the same real-time features found on high-end portable GPS devices like weather and fuel price information."

Garmin Mobile PC features the same interface found on the Garmin nüvi and StreetPilot range and the same kind of full feature set you'd expect from a standalone device.

Garmin Mobile PC is available in two configurations – a software only package and a bundle with software and Garmin’s new GPS 20x sensor.

The GPS 20x is a high sensitivity GPS sensor with a USB connection that has "non-skid" pads for dash mounting and measures around two inches in length.

The Garmin Mobile PC with GPS 20x bundle will be available in April for $99.99, while the software alone is $59.99. No word on UK pricing or availability.
