Right re-installed the SW, got the screen to say it was successful, then the RNS re started itself came up with the VW logo screen and then went blank, nothing at all on screen.
So what to do.......................
So I thought I'd load the map DVD into the drive and see if that made any difference, so still with the RNS blank but powered on, I slipped the DVD in and all of a sudden the RNS spring to life
, Radio and then checked the maps all is well.
Oohh and Darren
....... the MFSW is now working with the RNS510, so it was the firmware in the end
So all good now
Thanks very much for all the support and help chaps
