Not recommended purchase, defective series of GPS in this range of TomTom

This GPS lit once. Since, you can not turn it back on, connected or not to a power supply.
After some research on the web, other buyers have had the same problem ...
There must be a series of defective devices. It was chance that you will or will not in proper operating condition.
Very disappointed with this purchase because the quality control is not carried out before the sale. I recommend this series of TomTom car purchase too risky.
