Hi I have just retro fitted an RNS 315 DAB unit into my 2012 Golf GT cabriolet and have a couple of questions.

1 - Can I fit a rear numberplate light cam (have a socket in the back of unit (see pic)) if so where can I get a plug for it (already have cam (removed from my EOS)).

2 - Are there any firmware updates (mine is a 2011 unit).

3 - How about map updates this unit has five digit post codes would these be updated to six on latest maps or is it a firmware fix.

4 - Do all these units support voice activated phone or only mid 2012 onwards units,( I have used the original Bluetooth unit under the drivers seat and turned of RNS 315 bluetooth using VAG COM.

5 - Just thought of another question can you download speed cam POIs onto this unit

Many thanks. Mick
