Tach together, here’s the next question. I need an AHK, it’s supposed to be a removable Westfalia. Has anyone ever installed it themselves? If so, does the E-set have to be up to the A-board or just the trunk? Does something have to be learned afterwards? If yes with on-board equipment or only with software possible? And what does the warranty say with that? I know….let the dealer install….but I’ve done it 3 times and I can do it…..from time to time there are screws j a also fun. Would only like to order one before I have clarified the questions above, not that for some reason I need an Ori. from the dealer. Thank you in advance.
