TomTom and Renault have issued an update for their Carminat partnership which comes embedded in certain small and medium cars and offers satnav functionality to drivers of those vehicles.

The update brings IQ Routes technology, which plans the fastest route for a given destination using the driving history of millions of users, and advanced lane guidance, which offers help for motorists who get stuck on difficult and unfamiliar junctions where they have to cross multiple lanes.

The update comes on SD cards that contain maps. If you're a Carminat user, you'll get it when you buy your next map or activate your latest map guarantee, which allows you to get the latest map for free within 60 days after you first use their device.

"Now users of Carminat TomTom can have smarter and safer routing by easily downloading the features themselves – a first in the automotive industry", said Giles Shrimpton, TomTom’s MD automotive. "This is an important milestone in our ongoing drive to help the automotive industry meet the needs of its customers".
