I was just smiling to myself when I looked at the map and realised that one of my proposed routes from Austria to Slovenia takes us through the 'Karawankentunnel'. However, I then realised that the border runs across the middle of the tunnel, meaning that half of the tunnel is in Slovenia and will be subject to tolls. I had been planning to buy the DarsGo unit (we are over 3.5t) in Slovenia but I wondered if I can get it before we leave Austria? Has anyone done this route?
