I have a bluetooth OBD2 interface and I guess it's "one of the better ones" because it talks to the transmission computer in my Nissan whereas they tend to not do that.

Do you need a particular interface or do any of them work? I'm wary of paying for a month of service to find out I need to buy another adapter. It does connect and talk in the app but without a license I can't really do anything.

hard to say, carista seems to have it locked down a bit. carista wouldn't see my MX OBDII adapter that reads all the secondary computers in my other cars. that is a business choice by carista.... it sucks.

I guess I could always try it and cancel it if it doesn't work. I don't know if the Carista adapter does anything special like the OBDeleven one which seems to be the only one compatable.

Edit: I just found a blog post by them that says if the app talks to the adapter and it doesn't support the full ELM327 instruction set, it will say so - mine has not said anything like that so maybe I'm good.

yeah, full support is the issue. some chips don't support it. I found an app for droid that measures compliance with ELM, fairly handy. mine is full support. some of the app vendors have locked the software to their hardware to make more bucks.
