Help guys, have just Mate, I fitted the rns 510 into my golf exactly how they said on the golfgtiforum and it was all good for a couple of minutes. Then the car just went funny, radio went off. Climate control wasnt working and an airbag light came on the dash! So i thought it must be something to do with the new radio, so pulled it out put the original back in exactly as it was and everything seemed to be ok but when i try and start the car, nothing happens. Like the batteries dead
