Well the highest you can to on a mk3 is SW 3-1/63 And thats version 23-28 i think. I just did the upgrade it was very eazy worked like a dream. You will need some good quality cds and download the Mk3 V-23+ and then download clone cd and alco 120% and could somebody post this man the link to the instructions and a link to the downloads because i know it was hard to find when i was doing the upgrade.

thanks
