TomTom Go 930 Traffic in GPS / Satnav

Another small addition includes the ability to quickly mark the position of locations of map errors. This is used in conjunction with TomTom's MapShare tool, which allows you to correct map errors, upload them via TomTom Home and share others' corrections in the process.

Apart from these improvements, it's the usual high-quality TomTom fare. The speaker is loud and clear and the screen performs in bright light as well. There's automatic ambient noise and light sensing, full text-to-speech on minor as well as major A-roads and motorways, an FM transmitter, a Bluetooth speaker phone function that will also read out text messages, speech recognition that actually works, even in a relatively noisy cabin, and a speed-camera database installed as standard.

The user interface remains responsive and intuitive too, featuring the incredibly useful user-shortcuts page, allowing you to set up quick links to the functions you want to get to quickly. And performance in route calculation and time to GPS fix is superb too - we were rarely left twiddling our thumbs even for complicated multi-stop routes to be calculated, or while the GO 0930 Traffic scanned the skies for satellites.

It all adds up to an excellent navigation device, and one that is quite clearly the market leader in all respects. The only question is whether or not it's worth paying for. The 930 Traffic is probably overkill - the price certainly is - and on that basis we can't really recommend it.

However the model just below it in the range, the Go 730, is more reasonably priced at £260, and is identical in all important aspects. Once this become widely available, it will fall in price - and we'll have no hesitation in putting it straight on the A List.
