I want one for my 2019 which will let me fiddle with the "Dealer settings" I see them now from 20 bucks to 200 bucks. I am happiest 100-200 bucks.

what are the dealer settings you are looking to change?

Nothing in that price range will talk SSM protocol.

I heard that the Torque app supports SSM. Is this true?

Yea, I don't think you can access any dealer settings with anything that cheap.

 

Any ELM bluetooth dongle (I've bought a couple for ~$15) and an android app can do a lot of diagnostics. ActiveOBD is a subaru-specific app that can read transmission temperature, AWD %, and more on the newer models (was invaluable when diagnosing a torque converter solenoid on my mom's 2012 CVT Impreza).
