Navigation system for golf plus v

[scipi]

I am buying a new navigation system for my Golf Plus to replace my RNS300.

Options are:

Pioneer AVIC 9110BT
Zenec NC 2010
Siemens - RNS 510 MDF3 (reconditioned & no bluetooth)

All cost around Euro 1000,00 fitted, the Pioneer and Zenec seem to be far superior to the RNS 510 function wise. All three seem to be made in China and both the Pioneer and Zenec are specificaly made for the VW group.

been told by some that the Zenec is trash and by others that the Zenec is the next best thing to sliced bread.

Any advise / recomendations are most welcome ?

The Pioneer looks good as does a JVC unit I was looking at but none of those around seem to have DAB and there is no way I am buying a new unit without integrated DAB.
