For just $38.50 a month Telstra will install a small tracking device from Navman Wireless into company vehicles which will connect with the Big T's Next G wireless network.

The system transmits continuous information showing a vehicle's location, time spent at a location – heaven forbid that that might be the pub – speed, idle times, driver time sheets, unauthorised vehicle usage and vehicle maintenance status.

An inbuilt GPS satellite continuous pinpoints the vehicle's location; the data flows back to the business HQ via Next G.There's no capital outlay and the monthly payment can simply be added to a business's Telstra bill.

For an extra $38.50 a month, Telstra will add a screen and keypad so drivers can receive turn-by-turn navigation information and exchange messages with the dispatcher.
