Hi all,im fairly new to the site so this is my first post.I have just bought a 2007 gttdi 170 after losing my 2006 Jetta with every option on it to my ex,now i have already retro fitted the sat nav and have got myself the mfsw from ebay,i have read and re-read all the posts on the subject but am getting more and more confused as to what parts i need,i know i need the air bag harness part number 1ko-971-584 but what else do i need to get and what part numbers,i have not had mine apart yet to see what number my module is so just want to know if there is a definate part number i need? I am also going to fit the cd changer in the armrest instead of the ipod dock as i dont own an ipod.Many thanks for any help given,regards Alan.
