Actually, since I posted the above, just out of curiosity, I hooked mine up to the Autel site and was dismayed to see that they no longer provide tech support for this model...
TBH, if you are keen on doing this sort of stuff yourself, I would opt for either a later model, or even another brand.
Foxwell make some good stuff, but at a higher price.
Sorry for messing you about...my model does work fine, but you may want more functions than I am used to.
