Thank you very, very much Trev, for this unique project and sharing it with me.
And also I appriciate your support about the small issues I faced during my install.
I am using it on my carpc installed on a X1 20dx, and now am so happy having your hardware and PI.
I stongly suggest every bmw owner(with KCan) to give a shot on this one, Superb!
PS. I will share my carpc install here once I complete tidying up my trunk.
