You can get the code from VW for free give them the code that begins with VW** i think it is, and some 07 on cars have an upgraded canbus already best way is to check with vcds or take out the canbus and get the part number to see.
(also you can add an aux to the rcd310 easily)
Ah that's great, thanks! Will give VW a call when I receive the radio.
I've got a 06 gti so think I will need to replace the canbus
Ordered the Aux input aswell, got for £4 on ebay so can't complain!
