I know it's subverting the car's security stuff but has anyone seen the canbus conversation between the 9-5  IHU and the car that validates whether the IHU is permitted to be used in the car? I'm trying to work out who the actors are (Twice?) and who initiates the check.

I'm wondering if there is a way of bypassing the check - there seems to be an increasing number of head units that are forgetting who they are and need remarrying with tech2.
