Fmcheca. The are tho different solutions on the two different forums. Zerbino propose generally the soft solution using the MDI gate. Timur says about AMI box and asks more hardware changes. But the both solutions are possible to be realized in premium head unit without additional hardware upgrade.
As far as I understand the both solution demand only firmware update in case when you add AMI or MDI to you system. Of course, if you 'd like to use premium main unit and we have got common one, you will have to change it.
But you need the upgrade firmware in any case.
