Top mobile sat nav software

You can currently download a 30-day free trial of Telenav for your Blackberry, after that it'll cost you from 20 for a three-month usage package.

The software comes preinstalled on a microSD card so you can swap between different Windows Mobile devices easily - providing there is a microSD card slot on the device.

One advantage to Co-Pilot's satellite navigation solution is that you can fully preview your route before heading off, so you can judge any traffic hotspots or problem areas such as toll roads.

Co-Pilot 7 supports 7-digit postcodes and includes fully updated London congestion zones so there won't be any surprises when you mistakenly venture into a charging zone.

It now comes pre-installed on most Vodafone devices with GPS, although it will cost you 5 a month if you decide to continue using it after the first month's free subscription.

The Vodafone Find&Go subscription includes voice turn-by-turn navigation, free camera safety alerts, plus the ability to share your Points of Interest with your colleagues who also use Vodafone Find&Go very handy if you're setting up a business meeting.
