Will my Ross-Tech Twin-Com Interface work with a GM if I have the correct Software?
 

I know Ross-Tech's software will not work but was wondering in there is software available that will work with the Twin-Com interface in a GM?

Thanks!

No, see this page:

I've read that. Wasn't sure if it was the SW that was not compatible or both the SW &amp; interface.

Did you read this section?
 

"There are three different hardware standards for OBD-II. Interface Adapters that work with VAG-COM only support one of these, ISO-9141. The ISO-9141 hardware layer is used by most OBD-II compatible cars produced world-wide except U.S. Ford and GM products. This test is useless on U.S. Ford or GM vehicles."<ul><li><a href="http://www.ross-tech.com/vag-com/tour/obd-2.html">http://www.ross-tech.com/vag-com/tour/obd-2.html</a</li></ul>

Thanks.

I used the cable on a MB and a ford with another program
 

and as stated it worked with the MB and not the Ford.
