Hi, I purchased my RRS in the US and have since relocated to Europe. I just purchased the EU map from Landrover which arrived today via a usb stick. I thought the process would be straightforward but after it failed to read the USB stick I read online that the EU maps are not compatible for US models! I am not sure on the technical reasons for this. Does anybody know how I can update this vehicle navigation from US to EU? Do I have to replace a part? Any help would be appreciated, I am due to go on a tour of 16 EU countries so really need this navigation to work?
