Quick update. Software and interface arrived tonight so I have not had a chance to really dig into it as yet. The install was a snap and it connected right away to my wife's S40 which had a check engine light. I was able to read the pending code ( something about the coolant temp sensor reading too low) and reset the CEL. Also was able to connect to my rental (2009 Cobalt). It only supports OBDII. Unfortunately, I cannot test it on my car since it is in the body shop (rear end got rearranged). I will keep you updated. If you want to test it on your car let me know. We can work out a time and place.
I tried attaching a screen shot of it connected to the Cobalt.
