few flaws

The Navi I really liked it very much at the beginning.

However bothered gradually following:

1. The speed display in Navi was always clear (ca.5-8 Km / h) under the actual speed traveled.
This was tested on 2 vehicles at different constant speeds.
That was too critical for the warning of speeding.
May be a fault in the device?

2. The target directions were not announced but only displayed.
eg "" Take the highway direction Oberhausen "lacked" the spoken Additional direction Oberhausen-.
This is useful, particularly for young drivers. I found the menu no setting for this purpose.
Our 4 year old MEDION can.

3. The route plan is for me not optimal (at least in testing here in the northern Ruhr area)
At the fastest route, the highway - also with detours - preferred, although it is much faster routes, which are then shown in the alternative. But why not use the faster route is then displayed as 1.
In the shortest Put the NAVI is rock hard and plans and if possible a straight line A to B.
Unfortunately, the eco route planning has brought nothing, there was no difference to the fastest in my tests.

Unfortunately, the navigation can not be considered a "fast or slow" vehicle also. That means I do not want to be always directed to the motorway,
if I'd like to drive relaxed with our small car.

The new route while ignoring the planned route takes far too long. The NAVI are still pointing to the contact or leave when a good route already is gone.

4.The update has in a line adsl2000 he lasted almost 5 hours incl. The sit out of the 99% hanger.
Eignetlich I use the Navi only in D and neighboring countries. Would be good to shorten the upgrade time in targeted selection of countries (wishlist)
I need to upgrade it is not always all countries.

It is difficult to find a suitable new NAVI. Somehow everything NAVIS a weak point, if you can trust the reviews.
