Wow Pete! That's a better answer than i was hoping for. I assumed the DME stuff and the same with the DSC stuff i guessed you could just flash it and i was in the process of securing a spare before i gave up on the whole shebang. Can you confirm that its just a normal flash job via the standard tools or does it require some trickery?
Also theres a whole swag of people that would pay to have the /M drive working properly so if you want some cash......
Lastly, did someone help you with this or have you just figured it out for yourself ?
