Hello together, I did it! After a long time of thinking, I hit and bought a Phaeton W12 built in 2003 from serious possession. First owner was VW AG. Everything in it is possible. Now I have a few questions that you might be able to help me with. 1: Can I retrofit for the RNS 510 Bluetooth? Had an A8 before, which was possible via an adapter without any problems. Does the electronics play with it? 2: Is there the possibility to cut the limit at 250 km/h? Is it possible to restore the analog TV reception and perhaps also play it via the rear seat entertainment? 4: The FB of the heater is not available. Is there any accessories for it, or does it have to be ordered from the dealer? So that’s what I think it would be for now. Thanks in advance for your answers and help Greeting Ingo
