With all the extras TomTom shovels onto its flagship sat navs I thought it may be running out of ideas, I was wrong. The launch this week of the TomTom GO 730 and 930 (below) sees the addition of two extremely clever abilities: 'IQ Routes' and 'Advanced Lane Change'.
The latter is relatively straightforward (visuals are provided of complex junctions and road signs to help lane positioning before turning), but the former is ingenious. What IQ Routes does is keep a constantly updated record of historic average traffic speeds for more than 6.2bn miles of driven roads and use this to help equate what will be the fastest and most efficient path home at any given time.
Impressively, IQ Route even breaks its traffic data down by time and day so it can advise different routes for the same journey depending on when you leave. Even elements such as numbers of traffic lights, roundabouts and speed bumps can be factored in.
Aside of this, little has changed from their predecessors - the 920 and 720 - and each features a 4.3in 480 x 272 pixel touchscreen, zippy 400MHz CPU, Map Share and FM transmitter to play music and navigation instructions over the stereo. The 930 comes with 4GB of onboard memory and pre-installed maps of 35 countries in Western & Eastern Europe, USA, Canada and Russia. The 730 has 2GB of onboard memory and UK and European mapping.
Both go on sale at the end of April with prices to follow. Until then titillate yourselves with the demo pages for both new techs...
Update: There's a third member now, the GO 530. It also has a 4.3in touchscreen display and Bluetooth along with a 400MHz CPU and lower 1GB of memory. Mapping will be regional and there's no word if IQ Route or Advanced Lane Change make it onboard (I suspect they have). Expect the 530 also in April for approx £235.
