well I was one of you who downloaded gm 7.0 I went back to 6.01. So I downloaded 7.01 this morning. Today I did 2 gm`s a 08 silvarado with a ce light. It gave me 2 codes p0420 p0446. cool.I did a 14 silvarado no ce light. No codes found. cool. Looked around a little bit seems ok. If you have 7.0 this a good thing. To be determined if it has bugs but it read both vins and i had no problems. enjoy gm back thank you autel for the quick support.
