I am the owner of an older appliance Becker (Traffic Assist Z 205), which slowly goes to a good 5 years of service to retire. During navigation, the unit depended on increasingly. Whenever another 300 meters were displayed after a good time was nothing.
Restarting the device or to factory settings, provided no improvement. So I tried it again with a map update for about 70 euros - without success.
Thus I came (again purchased from Amazon) by a loan on the TomTom XL IQ Routes Edition 2 Central Europe Traffic navigation system incl. TMC.
Initially good things my joy was gedrübt quickly on the device. In the first tour, the GPS signal was found only after a good 15 minutes - which was not so bad, since the start of the route was known.
In the second use (a shorter distance) I was honestly 550 meter to the signal. From start to finish it is about 25 km. I nutzet alternatively my smartphone, which navigated me to the destination.
Unfortunately arrived at the TomTom moreover, that the changing of the night mode spinnte and the ad was green to neon green.
The device has been reclaimed by Amazon and it was an easy withdrawal.

After this experience with the TomTom, I decided to re-buy a Navi Becker.
After some comparisons there was then in this model. Well in a nutshell: unit with display and functions everything fine, except for the most important --- the GPS SIGNAL !!! On the highway road to Dusseldorf went in "every" trace the signal path tweilweise it took several minutes to the Singal was found. Then, a tunnel has been displayed, which came only a few kilometers later - then hung the device while the tunnel display and a restart was necessary. When the GPS signal in the "box" is time schauts good ... but unfortunately after a few kilometers away you go back and you can see a map without details! For the rest of the way I turned the unit off annoyed and thus came to the aid here again the smart phone to use ..
For software, there is only so much to say that it is simple. If you know where to find what goes well with map updates, etc. However, this also depends on too often. My old Navi I can not update, for example, because the program will freeze. :-(
I am very disappointed with the device. I'm now even test some routes, but I think that I will send the device back. For me the money is then too bad.
