Ian I'm just messing changing and RNS510 into a Columbus at the moment, I am just finishing off putting the firmware on and the splash screen is now the Skoda version.
It just needs the lighting changed? Yes its been done and yes its easy enough IF you know what your doing. It cannot be bricked just by messing with the front panel, but IF you don't know what your doing then obviously you can knack the screen and front panel up which goes without saying really.
You can have this unit for what I paid plus postage which was £460 plus £15 postage
Or I can change it back to VW and just get rid to someone else so no pressure mate

*****Small Update*****
I have found someone who will do the lighting change for £50 but takes a little bit of time.
To be honest for the amount I need for the unit and then the change you would probably be able to get a newish C version LED Columbus??
