Hello dear community, I bought a VW Phaeton V6 TDI with first registration in 2008. So the GP1. I have the following problem: The navigation system installed in the vehicle is the last shit, a reasonable interface for my iPhone is not available either. You can retrofit such a module from China apparently only with the GP2 and newer with the RNS 810. My question is, there is a possibility… 1. to install the RNS 810 from the successor model into my GP1 and this afterwards with 2. are there other compatible radios/Navis or even interfaces or additional modules to install? It would be an absolute dream to have this car Aplle CarPlay and to be able to use it fully… I hope someone can help me and thank you in advance.
