Wow! I recently installed an ATOTO A6 A6Y2710s stereo in my car. While going through the manual for the stereo, I found this Bluetooth OBDII Scan Tool as an option. They were only around $20 USD on Amazon so I bought one just to see what it would do. Installation only took a few minutes. I plugged it into the OBDII port in my car and paired it to Bluetooth #2 on my ATOTO A6 stereo. Then on my stereo, I downloaded the Torque Pro app for $4.95 from the Google app on my stereo. The hardest part was the download even with a strong wifi signal going to the stereo. I had to reboot my stereo to get it to complete the download. But once it did, THIS THING IS AMAZING! Not only do you get a full set of real-time gauges, but the app can also calculate 1/4 mile run times and horsepower. Basically, for the price of this little scan tool and the Torque Pro app (about $25 total), you get ALL the functionality of a $100 Autogauge, a $50 OBDII trouble code scanner and a $200 DPIC gauge. That's what I call a huge bargain! So if you have an ATOTO A6 or M4 stereo, you really should get this OBDII scan tool and the Torque Pro app. It's a great value. I'm still floored at everything this equipment will do. ... show more

    • It was an accessory to the new system we installed.
As far as I know, 1st hand, is that it activates a chip in my new radio that alerts us to upcoming rail road crossings. The distance is very close, and knows if we are running parallel to or driving towards a crossing. So as far as I am concerned, it does, for me, what it was designed to do

    • Works good but some features are miasing
Works wonders, is a bit slow to initialize, does not pull TPMS from ECU like it should (requires a costly value stem cover to do that), also when using it there is no way to turn off the blinking lights, is annoying and distracting when driving at night to have a flashing light in your field of vision. ... show more

    • Won’t stay connected to Bluetooth
Junk I purchased two of these, one worked maybe 3 weeks, the next one, only two weeks. One I returned & they refused a refund. Do not buy, NO instructions or information or any hint how to make this work.. I was connecting to an Atoto S8 so should be easy. Took about 1/2 hour to do what should have been a half minute job..connecting to Bluetooth. I did all the steps offered in other reviews…waiting 30 secs for it to establish communication, tried opening Torque app and then plugging in OBD2,,etc. I do not know what finally worked, but got it set up an working… BUT then turned off car..and when I came back, I could not get it to connect to Bluetooth and the Atoto dispaly again. Looks like I will have to return. ... show more

    • Works with ATOTO A6 but can work in other vehicles, too, using your phone with bluetooth.
Review Image by BryMelSmith
I bought this for my ATOTO A6 radio. I leave it plugged in at all times. Great value for the money. It reads the check engine codes and even looks them up on the internet for you. When you load the TORQUE app, it takes about 30 seconds before it starts reading the car's computer, but then it streams all data live in real time. It also displays all of the engine stats live. Such as MPH, Fuel level, MPG, RPM, you can customize what to show and how to display it. The adapter even works with your phone via bluetooth, so you can use it on your other cars, if needed. It reads hundreds of stats - you will never use all of the features that it has, but it is great that it has them all. There are even displays that save your maximum and minimum readings and you can set warning alarms. In case you are watching the engine temp or just timing your best 0 to 60. ... show more

    • Easy DIY/Glitches/Great sound
I liked the fairly easy install, love the sound (esp. w/new woofer), but the MFr glitches. If I'm listening to online music and get a phone call, the music app glitches on hangup. I have to close then reload the whole music app after every call. Also, after less than a year of reliable service, it gave me a static screen for about 15 minutes before it began a long series of auto-reload and self-check loops. Sometimes I can listen for the 20 minute drive home from work, sometimes not. It can loop for the better part of an hour, give a minute or two of music, then get loopy again. This has been the norm for about a month or more. To be fair, it could be a loose wire, but it doesn't happen during bumpy rides in my Wrangler any more often than normal. Well, now I've just confused everyone. It's a great system when it's working, I guess. You decide. ... show more

    • Nice little gadget
Very nice device and value. Provides a lot of information and easy to use with the app. Pairs nicely with my Atoto A6PF.
