Hello, I'm new to the VW world. I have a RNS510 and I'm not sure as to what version it is (A, B, C?) nor do I know what version firmware it is running. Can I just burn the firmware update (I think it's 3680) and put the cd and run the update? The instructions on this thread don't say if there is a sequence of updating the old firmware to the new one in order.
Also, do I need to do any coding myself as in VAG-COM etc? Thanks so much, so far, my 2009 Passat is amazing to drive.
