I decided to buy a new navigation device, a Junsun. 7inch

The Toolbox of Naviextras however is very confusing, I can't find the type of apparatus in the list.

The device is visible in W7, but the Naviextras toolbox doesn't see the device.

Second problem is that about half the menu's are still in English although set to Dutch.
I can read English, but it should at least have the proper languagefiles installed.

Now updating the device won't work since the device is not recognized.

When I try to update (Content for Navi extras) with the device itself through Wifi it says:
