Hi All, And thanks for the SatNav info. I have successfully upgraded my Mk IV to v31 from sw4/1-40 which i think is v24.

Everything works but when selecting cd tracks with the up/down buttons on the steering wheel i noticed the cursor on the SatNav display moves up and down over the list of the 6 cd's in the changer. i am sure it never did this before. i think it just used to sit over a cd in the list and not necessarily the one that was playing!

Is this just a feature?
