Anyone done this recently?
I'd like to update the maps on my unit in the van.
Hey mate - have you managed to sort this out?
I myself am trying to figure this out, so thought Id revive this thread after the awesome response you got the firstime round.
I did find this on my journey to here - https://paulroberts69.wordpress.com/2015/10/01/upgrading-firmware-and-maps-on-vw-rns-510-satnav/
May or may not be relevant to you ( not sure of your model)
Good Luck
