Micro Mechanic does connect with my 2012 Chevrolet Impala and does not connect with my 2004 Chevrolet Suburban. The only thing it does is show the pro-live dashboard and the Performance Timer. Even though I do have errors with the electrical system, A/C system, and engine faults, it does not display them. It continues to show "no problems found" and "safe to drive." I did pay for Micro Mechanic and the Pro App Upgrade.
Also, the following apps advertised to work with the Micro Mechanic on the Micro Mechanic Web site at https://www.getmicromechanic.com, do not recognize the Micro Mechanic OBD-II adapter: MINI OBDII, CAR SCANNER ELM OBD2, CARISTA, DASHCOMMAND, OBD CAR DOCTOR, TORQUE. The app OBD AUTO DOCTOR does connect sometimes, but when it does, it gives no information on faults.
DO NOT purchase this item!
Bottom Line: No, I would not recommend this to a friend
