Hy, in the Seat Altea XL from 2011 changed an original built-in radio (RCD310) for a RNS310. At the picture above is the original old and below the new. Antenna connection I then changed, funny construction… OK the car had before no Navi & no phone (only on the steering wheel the keys). Now everything connected and installed. It was called yes, that my car (how do I believe all the Seat this year) in the radio antenna also integrated the GPS antenna (whether it really is ?) Ra dio go Media goes steering wheel control goes problem 1: If you press “Phone” on the radio or also on the microphone symbol on the steering wheel, it unfortunately only goes “Mute” no more. It does not come the telephone menu, as it should be, then you can make the settings (couple with mobile phone ect.). Why not, what can be there ? Problem 2: Navi, you enter a destination, he recognizes it and calculates the route. You go and the red cursor in the middle moves also with the car, reacts to curves ect. (so he should already have GPS, because how does he recognize the vehicle movements?). But he does not recognize the location, he thinks he is 900km away, and the map in the background is absolutely not true, he drives next to roads, over fields ect. Why is this so? In the back of the new radio is a blue plug, I first thought this was just for the GPS antenna, and tried using a new GPS antenna that I still had to plug in, but the plug is a complete What exactly is the blue jack on this device? And what does it have on it that the navigator doesn’t radio properly? Can it be that I have to go to the VW and these have to tell the radio first that it is in another car, or how (but for what then the code ect.).
