Hey. coming back onto the thread after some time, hopefully someone notices. Can someone explain how do I install this onto my Audi? There's two DVD maps, is it necessary to burn BOTH of them into the same DVD? Will it function with only one of the maps burned onto DVD? When burning, do I put the original .iso file inside the DVD or burn what's inside of it? When uploading the maps, do I somehow need to uninstal the old map or just insert the disk, download the new one and it's all good to go?
