Review on ATOTO AC 4450 Bluetooth Diagnostic Scanner by Justin Goff

Wow! I recently installed an ATOTO A6 A6Y2710s stereo in my car. Searching the manual for the stereo I found this bluetooth OBDII scan tool as an option. They're only about $20 at Revain, so I bought one just to see what it would do. The installation only took a few minutes. I plugged it into my car's OBDII port and paired it with Bluetooth #2 on my ATOTO A6 stereo. Then on my stereo I downloaded the $4.95 Torque Pro app from the Google app to my stereo. The hardest part was booting, even with a strong Wi-Fi signal going to the stereo. I had to restart my stereo to complete the download. But when it does, great! Not only do you get a full suite of real-time sensors, but the app can also calculate 1/4 mile time and power. You get ALL the features of the $100 Autogauge, $50 OBDII Trouble Code Scanner, and $200 DPIC Sensor. I call that a huge deal! So if you have an ATOTO A6 or M4 stereo, you should really get this OBDII scanner and Torque Pro app. This is great value. I'm still amazed at what this device can do.
