Anyone tried the latest update or know whats in the latest update?

It's an updated data version, this is something we do regularly to keep up with changes VW/Seat/Skoda and Audi make within the model year.

A data version usually contains new/updated label files for newly introduced models/control modules as well as new/updated label files for older models where our documentation wasn't complete yet. It may also contain an updates Auto-Scan list and a new set of fault codes, both is the case with the latest update.

Don't hesitate in installing, it won't do any harm to you - updates are cool.

Is there a later update than Release 704.1 Data Version 20071016 which is the current version available from Ross-Tech's download page?

No, why should there be one?

cheers

I like the Bentley entry in the autoscan.txt file, or have I not been paying attention and it has been there on previous versions?

It was there on the previous one also.

Can anything from a 2002 BMW 320id be read through the OBDII?

The BMW should be EOBD compatible, give it a try - no guarantee though but I remember a customer confirming that it did work on a BMW 320d E46 10/2002 110kW (204D4).
