Has some useful featuresReview by Andrew
The GM add-on is a good addition to the Scan XL and I would say is a must. Without the add-on the main program will only read basic OBDII codes. Probably the best feature of all is the ability to read transmission data. That's because it allows for a series of sensors to output useful info and for a troubled tranny that's the way to diagnose it. I haven't had a chance to test a CVT but I would assume the program would tell something about its condition.

Does a good job when purchased enhancedReview by Vio
A superior diagnostics soft. Compared to ScanMaster (which is garbage) that I tried using before this one works flawlessly and has a nice user friendly interface. Now here is the drawback. If you buy the Scan XL as a stand alone program you might as well stick to your free OBDwiz.. Problem: it's too basic and limited , in that very few IPDs are displayed. Connected it to my Volvo but couldn't see much useful info, Equal to OBDwiz capabilities.
But... when I connected to my Saturn with the enhanced GM add-on I was ecstatic. I could see in detail what went on inside the transmission. Even the gear ratio. I was in awe. Also helped me to understand why the airbag light was on. Saved me $100 on airbag diagnostic. As for the ABS feature that was a letdown. Apparently only 2007 and newer GM vehicles have the ABS feature written for them. Disappointing as mine was 2005. Overall I am satisfied with the program. Useful to have when you know how to read the data and the graphs.
