OBC Hack isn't working

[seventythree]

I just finished the hack and only have partial functionality!
Two of the wires allow me to scroll back or forth through the basic information, i.e., outside temp, fuel mileage, average speed and so on. But the other two wires don't do anything, hence, I can't bring up the OBC menu to check or configure any of the features.
I enabled the OBC using the Durametric cable and software.
Before I go and start checking for faulty connections, am I missing anything here? Do I not understand how the OBC works, or did not fully activate it using the Durametric?

TIA
