In the 2nd run perfectly, then again failure.

Tom Tom VIA 135 ordered from Amazon. Delivery quickly and easily. First test of the device showed errors TMC receiver switches on at random and out. That's annoying in the car. Device to Amazon sent back asking for replacement. Waited only 2 days, then come Ersatzgeraet, talk about fast! The Ersatzgeraet worked once only as a promotional television, after about 3 minutes turned the box on a promotional film that showed a young woman placing the device on the windscreen. This is driving very informative, I want to see the map, not the advertising Chickse! After reset to factory settings and re-complete facility, the device was now fine, let's see how long ...
Addendum on 26.7.2012:
Again technical failure of Tomtom VIA135! This time, according to the map update (3 hours with DSL 6000) on the Tommtom page. Card has been loaded on the device, no more voice control was possible. Despite Landeswahl Germany and spokesman Yannik (computer voice) of Tomtom troetet only: Voice control is not available for the selected country ...!

Conclusion:
Positive points:
None. Apart from the fast delivery by Amazon and the quick replacement.

Negative points:
Hardware failure cable break or loose contact on connector
Imbeciles Werbeeinblendung during use of the driver distraction mistaken.
Map Update extremely complicated and very slow because you have to have good computer skills have to get you through this.
Tomtom software on the computer can not be configured (location, etc.) and is a permanent process to "phone home".
An apparatus according to map update completely "off the roll". Voice control is no longer possible, and not to activate by RESET to factory setting.
Response times to touch are measured in seconds, ie extremely slow.

Now I've had enough of Tomtom, products back to Amazon and asking for a refund. Therefore, absolutely no recommendation to buy, the TomTom Shop is mE a "cheese factory".
