I have downloaded the latest v2.56 update pack, which contains both US and EU subfolders.  Does anyone know what the differences are between the files and can either be used?

Thanks,
James

 I decided to give both a try.  The TS401 seems to happily accept either.  The differences just seem to be the choice of vehicles, based on the cars available in the respective areas.  Many cars are in both, though the classification is not necessarily the same.  My Jaguar has some year splits, a choice of 315 and 433 frequencies and the relearn information in the US file (same as was in v2.42), but just a single choice with the 433 frequency in the EU file and no relearn process shown.
