Ouch Duncan, an expensive add on plus unreliability is a bad combo.
There must be a manual for yours out there, if you go back in this thread you'll see one was found for my model. I can only suggest you pester the dealer. Surely his staff must have been on some sort of course for this.
Best of luck.
