He was very effective the first 2 years !! Gros use as a delivery driver PL, now it is virtually useless! Except that for updates and possible backup, do not expect help from Tom-Tom. Now as soon as he makes a sound it stops altogether !! So off voice guidance and danger zone but still leaving the famous word "Toll". Like all GPs battery consumption is at great speed so even plugged it takes its recharge start !! In short the price of the beast is especially sad that want to get it fixed back to buy another one !! Very disappointed yet I was a faithful home Tomtom. I do not even dare to reboot because I have no backup, I tried not an update of the card, too risky. So given the lack of respect for Tomtom they will still lose a client because at this price today I will have at least free upgrades elsewhere. A word.
