A couple months ago  I would have loved to have had this product sitting in my tool chest. I had  a strange combination of a check engine light and flashing stability control light - indicating a problem, but it took a while searching on Google to tell me it might be as simple as a loose gas cap (which is what it ultimately was). A couple of seconds with this tool would have saved me a lot of worry. Knowing how complex car engines have become,  I was excited about getting one of these tools to try out.

While I tried to replicate the loose gas cap error, so as to test this device, I just couldn't get it to trigger a malfunction. I CAN tell you that the software downloaded easily on my iPhone and synced with only a little difficulty to all three of our cars; a 2009 Subaru Forrester, a 2012 Nissan Frontier pickup and a 2016 Ford Mustang. In the case of the Nissan, I had to scan the bar code on the inside of the driver's side door, while the Subaru automatically pulled the VIN number and other data right off the car's computer. In the case of the Mustang, it didn't appear that the database was up-to-date enough to pull all vehicle information off the computer yet. It did, however, connect and show engine operations accurately.

There was a bit of confusion as to the steps to take to get the device to communicate with the car's computer. I had to experiment with combinations of hitting the sync button on the reader while checking the Bluetooth connection on my phone. It seemed like it took different steps to get each of the three vehicles operating with the software, but ultimately all of them worked perfectly.

Another great feature of this particular product is that you can save up to ten vehicles at a time and there are no fees to use the software - not all of this type of devices do that.

With the complexity of car engine control systems, complicated by emissions and such, this tool can be a valuable resource in any tool kit. Using this product just once could probably save you the full purchase price by saving you having to go to a mechanic and pay them to connect to their scanner. I highly recommend it!

It helps me pin point where trouble is, and lets me know if my local auto repair shop is being honest in their assessments. Worth it to be able to call up information. It would be good if this could interact with and display on late model cars with built in navigator and audio screens.

The way this device connects to Bluetooth is so troubling and frustrating it ruins the experience before you even get started.  There has to be a way to improve this connection process.

Most importantly, the bluetooth connection is inconsistent. It pairs, but will drop pairing unexpectedly. Also does not restart the connection and what was playing automatically. Would be helpful to enable such a function.

As a design element, the connection between the magnetic base and the bluetooth device is not as strong as expected, leading to it dangling off the dashboard at times. The wires are also excessively long. Overall, could be designed with retractable cords or method that would minimize cord clutter.

Do yourself a favor and buy a (more expensive) oem sensor, had one of these fail on me in 1000 or so miles just happened to be about 500 miles from my house on a road trip. Luckly I was able to make it home, purchased another one and still have a check engine light due to the sensor, BMW is very finicky with sensors apparently.

I've had a similar tool before, but at that time it was necessary to pull it from the car, connect it to a computer by cable, and then look up the error codes. This one with its phone app works great!

I'm not sure if my unit speaks for all of them, but I have had some issues connecting to the unit. It took about 15 minutes of unplugging and re-plugging and turning my car on and off to finally get it to connect and stay connected. It appeared to shut down mid-sync the first 10 attempts.
If this is an issue with the unit, then if a customer service rep could help me with a replacement I'd greatly appreciate it!
I really want to love this product, but I'm also confused as to the layout of it.
Also, I'm not sure whether I can turn off some of the car's features such as the warning beeps when a seatbelt is unplugged during use...especially when dinner on the passenger seat does not need a seat belt :)

All in all, I'm not sure for $99.95 that I got my money's worth, really wish it had a few more things to it.

My mother bought this unit for her car. When I attempted to use it I was stunned. I almost need to stop the car and get up close to the unit to read the lettering. Although it is a capable system, it was in no way designed so that it would be easy for a first time user to operate. I consider myself pretty tech savvy, but I found this unit to be very frustrating. I now make it a point to not borrow my mom's car just so I don't have to use this stereo system. Although pioneer makes some good products, whoever designed the user interface on this product botched it big time. My advice, buy another unit with larger buttons, legible lettering, and easy to understand instructions.

I wanted to read my Check Engine codes but it won't connect to the phone or tablet.
It may worth spending more and get a better OBD Adapter.

I purchased this to use for diagnostics on my Toyota Corolla.  Also used it on a Mazda 3 then gifted to my dad and it is still working great.  You can use an app called torque (lite) (free app) to communicate with it from an Android phone or an iPhone or iPad.  Using this app you can see any codes, clear codes, and have virtual gauges that show things like fuel mileage, rpm, and more!  I gave it away because I wanted to be connected to WiFi to look up codes and with this I had to disconnect then join my network and then reconnect.  So I purchased the Bluetooth version (different manufacturer) I also wanted one that had an on/off button so I could leave it connected an just push the button to turn it off.  This one didn't seem to drain my battery and seemed to use very little power so I may have been able to use this for that purpose.  I'd still be using it if I had an iPhone or didn't prefer the Bluetooth version.  I can't remember exactly but the password if you need one was 0000 or 1234.  It also seems like the WiFi version drained my phone battery faster than the Bluetooth one.

Instructions are poorly written. getting a correct frequency from unit to car radio takes a bit of timkering

God thinks: lots of hints, sensors verification with voltimeter.

Bd things: some specific hints, like how to change spark plug in V6 engines pr the proper abs module bleeding are missing.

just download the android app; play a bit with it to figure out the screens; then have your buddy drive the car and check the numbers during operation; so far so good

The car in general is Okay.  However, the major issue is there are only a few dealers anywhere around, and I cannot take the car to a service shop for simple service such as changing oil.  The warning signal cannot be reset which is annoying.
