Hello, I want to buy a 2009 Phaeton. I know from theseler that it is equipped with solar roof. However, I have read at the EPOC website that GP2 has the following feature: Solar sliding roof in conjunction with RNS810 ex factory without function. Does this mean that the Phaeton I want to buy can have the stand ventilation not operational? If yes, how can I check remotely with theseler when the stand ventilation works or not? Thank you in advance for your answers/comments. Arek
