Nothing about a tech 2 here but isnt it crazy how we ‘rely’ on our children (mine are 13 and under) for advice on ‘technology’ ... annoys me to no end when i need to ask my daughter how to do something on these computers/iphone/ipads/kindles...etc, etc
I'm tired of trying to keep up with Moore's Law. Been using computers since I was a kid but being forced to upgrade from XP and my S4 Mini phone have soured me on electronics. When I built this PC, I had to completely relearn everything as many of the terms and ways computing is done changed from 2005 when I built the last. Sure hope the Lord comes soon, I'm tired of this stuff!
I have no qualms having the little ones fix or program apps for me anymore!
As for the Tech-2. Well, my advice is find a seller with good reviews/feedback and make sure you get software version 33.004 and the CANDI module is you'r using this on a GMT-900 platform with the CAN BUS computer architecture.
I used to think they were the same as original save for stickers, coming out of same factory in China that made them for Vetronix. Some of that may be true but know that mine at least does not have same power supply. The only downside is the Tech-2 re-booting when starting the vehicle from key on. Hasn't slowed me down any though.
Regardless, you have to have one to work on these things and it will pay for itself in short order.
