Does anyone know which model of aftermarket CarPlay systems would fit and work in a 2011 M37x?

How would a after market system even work? Just curisous becuase of the way the console is set up. Screen then climate then radio at the base.

One does not exist.

CarPlay is still only available on OEM's and a very small number of aftermarket double-din units. I figure they will eventually make an add-on unit about the size of a Garmin that can be added to cars like ours. But for now, there is nothing on the market that will work in cars like ours.

The only other option is CarPlay activator for jailbroken iPad, iPad Mini, and iPhone 6 Plus. Check it out HERE then use Google to find more info on it if you want.
