I can not contribute anything to the device itself, but ...

... To the service behavior of TomTom.
My first was a TomTom Navi - I think the Go710 - for almost 500 at the time when I have not right in the head.
After about 1.5 years of battery was in the bucket, and he kept not even overnight the basic settings as selected color or the home base.
My request to ensure that battery was heavily if it were not included (about 6 months)
Grudgingly, I accepted the offer to repair about 100 since a similar Navi still considerably more cost.
And after one year the battery was down again.
As the request originated I do not need to explain further ...
I then asked if there was the possibility of an ex gratia price of purchasing a new TomTom.
Nope - I was referred a bit cheaper than the regular price on the Refurbished devices to one side were offered.
Well - I thought then that other fathers have beautiful daughters and bought a Becker.
I have now for 6 years, it runs smoothly, if there is a question - the support answers quickly. What the heart wants more?
And should there be a new Navi again it is undoubtedly another Becker.
