I have got RNS-E unit and i am mounting the unit in a Seat Leon Cupra R 2005 with CAN. But i have got the speed wire(gala) and illumination connected to my original seat stereo allready. Could i use the Gala insted of th can. Keep in mind that the unit is RNS-E for the A4. If i look at the pin diagram at the RNS-E there are pins for gala as well as for can. So is it possible to use the Gala even if the unit is supposed to be mounted in a A4 with CAN. Maybe i can fool the system bye telling it with vag-com that it is a A6 unit?
