In the competitive world of always-on vehicle tracking, the latest pricing from established player Navman Wireless represents possibly the most competitive offer yet. It is providing its tracking at a fixed price starting at just £7.99 a week all-in - and that includes vehicle installation, training, office-based software and street-level mapping of the UK. Exception reporting is also included.

The price includes an automatic position update every ten minutes. The rate goes up by 50p for five-minute updates, and by £1 or £2 for updates by the minute or half-minute. But users can make any number of manual position requests within the basic price, and set up any number of geofences.

Navman Wireless uses GPRS for data transmission and GPS for tracking, offering either an external or an internal Halo GPS antenna. It has now added a form of text messaging through the GPRS link, charging just £1.99 for up to 2 megabytes of texts (said to be the equivalent of 1,600 SMS messages). It offers its own handheld terminal, the MDT-800, for this.

Navman is based in New Zealand, where it manufactures much of its own hardware, but it has a wide presence throughout the world, including a UK base in Staffordshire.
