Elsewhere, it's the same top quality fare that made the x20 range so successful, with the occasional tweak here and there. Ease of use is superb, the maps update smoothly on screen, voice instructions are delivered in a timely manner and the speaker quality is quite superb. The 930 Traffic has speed cameras preinstalled, and there's TomTom's excellent Map Share technology, which allows you to correct errors on the map, and share others' online, too, via TomTom's superb Home PC synchronisation software. There's one key improvement here too: you can now add a button to the device's customisable shortcut menu to mark locations as you drive - this was one of the few areas I felt the TomTom Go 720 deserved criticism for when I first reviewed it last summer.
The 930 Traffic also has Bluetooth for hands-free phone calls (it'll even read texts out to you as they arrive) plus a Bluetooth remote control. It has an FM transmitter so you can connect the device wirelessly to your car stereo as well as sound and light sensors so the volume and screen brightness can be adjusted automatically based on the conditions in your car's cabin. And let's not forget that you can enter address details via speech recognition. Amazingly, as with the 720, this works brilliantly, allowing you to redirect to alternative destinations while keeping your eyes on the road and your hands on the wheel.
Last but by no means least, we come to the Go 930 Traffic's only downside - the price. Unfortunately, the price has shot up this time around and this is now the most expensive sat-nav TomTom produces. The 930 Traffic costs a whopping £400 - £50 more than the 920T it will eventually replace. Of course you don't have to buy the top-of-the-range model - the 730 Traffic has all the same features minus maps of Russia, Canada and the USA for £330, the plain 730 without TMC is £300 and the UK and Ireland variant less still at £280 and £250 for the Traffic and non-Traffic versions respectively. But the 730 is still significantly more expensive than the 720, for instance, and the 530 more so than the 520, which though coming to the end of their shelf life, are both still available online and can be had for around £180 and £160 respectively.
So are the additions worth the extra cash? For now, I'd have to say - surprisingly - no. The new x30 range undoubtedly maintains the 720's position as king of in-car sat-navs, with its improved route-finding abilities and lane assistance. But the changes, though innovative and useful, aren't the sort of major improvements you'd want to upgrade for, and while stocks of the x20 range still exist, the older models represent a better deal.
If you want the ultimate in-car sat-nav, money is no object, and you don't have one already, the 930 Traffic and its slightly less expensive brethren are most certainly the devices to beat. But I recommend you wait a while before buying one until the price drops by £50 or so.
