Carista exists in a space that is flooded by options. You can get on Amazon and look for an OBD2 reader and easily find one under $20. Pair it with certain applications and you have a way to diagnose what’s wrong with your vehicle at home.
Where the Carista adapter stands out though, is in its ability to let you customize your vehicle. Having upgraded from a 2004 Suburban to a 2016 4Runner recently, this was something new to me. In the past with my Suburban, I simply used an OBD2 adapter to tell me what was wrong with it. Now, however, I can use Carista to change certain options on my 4Runner.
Want the windows to all roll down when you unlock the car? Done. Don’t need the eco fuel economy bar on the dash? Done. The options are plentiful and most of them I have no idea what they do. Some are obvious and some are not. And some are listed that don’t even apply to my particular model.
Installation of the adapter is simple, just plug it into the OBD2 port on your vehicle. Download the required application for either Android or IOS and pair the adapter with the app. Once that’s done you can get some basic diagnostic and customization features. Pairing the adapter and the app takes a few minutes each time you start the application.
To unlock all of the features does require a yearly subscription of $40. This is on top of the $30 for the adapter itself. You can forgo the $40 subscription part, however, and use the adapter with a good number of other programs that list out vehicle information and diagnostics. I recommend the Torque app, while not the prettiest looking, it does offer a huge amount of information.
The application itself is simple to use and the learning curve is low. The interface is clean and easy to navigate with only three options being available. The tricky part is understanding what each customization option does and that will take some testing. The options for customization only differ from a timed option or a simple on/off option.
The only other problem I’ve had is using the Carista adapter with the Torque app for live readouts. The adapter works fine with Torque. The problem is re-connecting it with Carista. The adapter won’t play nicely with both applications at the same time. So you will end up having to re-establish the connection with one or the other depending on which application you’re using at the time.
In all honesty, this isn’t something for everyone. If you have an older model vehicle, check the Carista website to see if your vehicle is even compatible. As an example, my Suburban was only able to use basic diagnostics features, basic service features, and no customization options. Whereas our 4Runner has the ability to use all of the options. It’s a great, inexpensive tool to have if you have a year model that works with it.
