I have a laptop or two so for troubleshooting my 05 Silvarado I would like to use a laptop instead of a scanner. Can anyone recomend a software company for doing this? By the time I piece togeather a Snap-On scanner I'm pushing closer and closer to 1000bucks to have all the bells and wistles in a scanner...so laptop w/OBII connector is the direction I am researching now... Comments? Opinions? Thanks for your time Burt
