I tried looking for caristia adapter on Amazon but it doesn’t appear. Went to caristia website to buy and takes me to buy it but when I put make and model, Prius doesn’t pop up. I spoke to chat and they said it’s not compatible with Prius? Help!
I suggest you purchase another OBD and forget about the Carista. Not just because you have to pay a monthly fee to use the app, it doesn't come with the enhanced diagnostics feed. I say get an OBDLink, after testing the Carista and about 10 others, it is by far the best device for the Prius. New OBD2 Bluetooth Adapter is better than Carista - black_jmyntrn
It's not compatible with the app they're trying to sell you... That's the point they're trying to make. I have bought more than one carista and I can assure you they work great with Dr. Prius, Hybrid Assistant, Torque and many other apps. Carista's app is a gimick to charge you recurring fees. You don't need their app.
