Got it today. It works great. I was able to turn off the backup beeper and set the headlight timing. The only thing I found is to make sure is that the vehicle is turned on before having the software connect to the vehicle. If it's not fully on, only a subset of the parameters can be customized. If it reads the mileage and VIN number from the vehicle after connecting, everything is there and works. I didn't try many of its functions, but it can also run diagnostics. It's a very useful tool for less than $30.
