I found a guy that builds converters for cluster conversions, have to tap into the canbus line. It's built on arduino CANBUS reader that outputs to a elm327 standard bluetooth, any android reader will be able to connect to the elm327 it will act just like a regular obd2 reader

I owe him an email to confirm I want him to build one, he's done something similar for bmw's and I believe the protocols are the same
