Hi New on here and the proud new owner of B6 estate 2.0 TDI 170 SEL. Plenty of toys on there to be going on with but what I really miss are the steering wheel buttons from my old car. I was looking on eBay for a second hand wheel and there's plenty out there. I just wondered though, is is plug and play or do I need some kind of addition control unit ? The original is like new so I'm very reluctant to actually change it but if I find the right one in good condition I'll be a happy bunny. Assuming the swap would also be an easy thing? Disconnect battery etc..... Thanks in advance
