Hello community! In the next few weeks it’s time: I get the successor for my GP 1. A GP3 will become. Now my question about the heater or the heater: This heater is installed with every Phaeton. With my new vehicle the heater is also listed in the equipment list. But now I have the “new” Navi.-System RNS 810. Is it also possible to unlock and operate it? The coding should be the same, but I also have the screen user interface in the new Navi as well as in the GP0 / GP1 ?! I have looked for an answer in the many posts, as well as several times this question in the relevant thread, but unfortunately found nothing / received no answer… Of course I hope that with this xth contribution I will not fall to anyone and wish a pleasant evening!
