TomTom is offering "dynamic" route guidance with its latest satnav system - the GO x40 LIVE.
The device automatically connects up to TomTom's High Definition (HD) Traffic service so the directions it delivers "continuously adapt to changing road conditions and always gives drivers the fastest route to a destination", claims TomTom.
The service was already available in the Netherlands, but now includes information for the UK, Germany, France and Switzerland.
The new line-up comprises three models - the TomTom GO 940 LIVE, TomTom GO 740 LIVE and TomTom GO 540 LIVE.
The trio come with an extended version of TomTom's IQ Routes technology, which is now based "on historical travel time information for every road, specified for every day of the week, at five minute intervals".
The devices also come with safety alerts about mobile safety cameras - provided in the UK by Road Angel - and up to date fuel price information as well as access from the device to Google.
Also worth a mention are the voice command and control tools which allow users to plan a route or make a phone call just using their voice.
TomTom LIVE Services and the TomTom GO x40 LIVE series will be available in the UK, Germany, France, Netherlands and Switzerland from Autumn 2008.
Prices start at £299.
A free 3-month trial period for TomTom LIVE Services is included. Following this, users can register for a monthly, flat-fee subscription of £9.95.
