Most of the MK7 golf parts will not fit the mk5/mk6 without solder the circut boards, changing wirering etc etc since that car is total differeint build than ours..
I know someone who got the mk7 golf cruise control and wiper stalks fitted to a mk5. But that's alot of work since you have to trace the board signals to the functions from the stalk to mk5 base. So not something everything can do hehe...
The mk7 mfsw is still not plug'n play in the mk5/6 but by far the most easy mk7 item to retrofit
