Thanks for that, I will read the MMI this weekend and have a look. Im using INPA and DIS on my macbook using a virtual machine inside a virtual machine which is pretty slow! So im setting up a old computer in the garage at the moment purely for diagnostics etc...
Ace, do you have a list of hex values for the MMI that you know what they do? i.e. enable the various different options that I will need to program when I upgrade the MMI?
I will take a picture of the unit this weekend, The wiring sounds simple just need to find the diagrams for my unit and the new one i will be fitting and match the connections up.
