The Tech 2 that everyone refers to.
Is this a clone of it? Could that have similar functionality? The price seems reasonable compared to even a single visit to a mechanic. It seems a real GM Tech 2 is hard to come by and expensive. Figures. There is a green and black Bosch that seems like a real Tech 2 clone but it is also quite pricey. I am interested in a 2 way, and I guess I'd rather have a handheld unit that isn't wireless and that has as much of the GM specific capabilities built in. Under $300 would be great. I've looked at lots but they all make various claims and it's hard to tell which of them a blowing smoke and which might be useful.
I have a bluetooth dongle that I got for some other cars and for when I was doing my used car search. I have tried a few some phone apps. I found an app that reads most of the honda hybrid codes, but I am not generally impressed with the phone apps.
PS thanks for the replies so far, sorry it took me so long to respond.
