I'm back (safely,
@MRRSM ... thanks for the safety tips - appreciated - but it's not my first time at the CL rodeo)
Yes, folks, this is a real deal Tech2 - at least the main unit is (DAMN, is it HUGE!). It has the code on the inside of the data card slot, screen boots w/ no issues, and it remains connected when the vehicle is started. You can also see it's got some decent (but not excessive) wear on it; mostly on the 'down' cursor / enter / exit buttons up top. Guy said he was a retired GM tech, and you could tell he knew what he was doing with the thing as he demo'd it on the Voy. Nice guy. And he drove a Tahoe...
According to the video clip Mooseman sent, the CANdi *might* (?) not be legit - I looked at the female connector just now, and the pins don't especially look like silver / aluminum to me, plus they're recessed more, like the clone version that was on the video. But the main unit is legit & good to go; I'll check the CANdi unit again later, when I'm in the garage and have more light. No case, and no CD-ROM - but for the price, that doesn't upset me.
Now to start learning about how to use this thing (the menus are no problem; I know some things have to have a subscription purchased (?) in order to do them (e.g.; certain programming functions) - ? Short term subs are available. I was on the GM techconnect site, and they promote a free manual download...somewhere...LOL
Finally, for anyone in N. IL / S. WI - next time you need the services of one of these, send me a PM!
