We reviewed TomTom’s Go back in January and though impressed, the models were undeniably expensive. The TomTom One costs $764 – almost $350 less than a Go 300. It uses the same excellent routing software and few features are missing. While the unit is smaller and you can’t overtly add avoidances to your route (as with the Go), you can still easily add waypoints to a journey and choose whether to go to an address, GPS coordinates, point of interest, point on a map or (usefully) just a town centre (you don’t have to give an exact road name). Bluetooth phone support is pointless as TomTom’s PLUS services (weather and traffic) are not available in Australia. There’s no hands-free function as with the Go 500.

We tested the unit extensively by travelling around central Sydney and literally the Back of Bourke. It functioned well around the Sydney metro suburbs, but as with most GPS devices, struggled when tall buildings lined the street. Out of Sydney, usage was generally fine, though unsurprisingly many remote, low-grade roads weren’t listed. We were a little perturbed when coming down the Pacific highway, as just 300km north of Sydney we were asked to do an emergency turn down a phantom road while travelling at 100km/h. Unfortunately, the occasional aberration is normal with this technology.

Those with fat fingers may prefer the excellent Garmin StreetPilot c320 (Issue 98, page 64) as the onscreen keyboard is a bit small, but this cheaper device has more features and better software, meaning it’s the one to go for.
