As said before im an oldish bloke who has not got a clue all ive got is a car stuck in the garage with a totally flat battery.
So should I have a go at burning this disc (and chance blowing up my rns)
putting it in the unit when the batt recharges or go to Gt Yarmouth for help. or go down to my local VW centre and get them to do it.
Or should I just refit my old unit and re-sell the rns510.
As you can tell I get fed up pretty quickly, but you chaps have been really helpfull.
Many thanks George
