Knowing how many potential "alternatives" but wanting a good capable unit I contacted OBD star in china via their website.

It was a depressing reality of IDNGAF (from a company representative) with regards to both technical question of suitability across multiple vehicles & their "warning".

Basically they will NOT support / entertain claims made from folk other than themselves, not secondary sellers of official kit which makes the whole prospect of buying the genuine article pointless!

May as well buy a well priced counterfeit because the odds are that you'll get a sharp "NO" even if you did buy their actual product, plus on the technical front that "assistance" was totally ignored.

POT LUCK, Hobsons choice!
