Mark, The computer was bought on a specification as recommended by the software seller and was set up by a young man that is well versed in computer and software set up. It all talks to each other, once plugged into the car, and is just a case of spending enough time and patience with the darned thing to actually master how it works. I have heard, despite being told it is about the best you can get, that it is somewhat complicated to use until you are used to it. I did manage to find a Jaguar document on the internet which is plainly not the easiest to understand. It consists of some 3000 pages on a pdf document and as far as I can see it is a "teach in classroom" and not a "teach yourself Job". To read the document and understand it without someone who knows it teaching you as well would be a life times work for me. My son in law is reasonably astute with Computers and he is going to see if he can get to grips with it. I doubt much will get done now until the New Year.
Cheers, John
