From the graphics of the menu and the model number, I believe my 2013 911 has the isudar aftermarket CarPlay installed by a previous owner however I think it might not be wired correctly (when I receive calls and answer via CarPlay, the person on the other line says they can't hear me, and the rearview camera that is installed does not appear and the owner told me they wired it incorrectly).
I am still in the honeymoon phase of ownership so I don't really want to mess around with this myself just yet so I am trying to find a place around Dallas that has experience installing/wiring/diagnosing these.

Any recommendations? (I live in Dallas proper if that helps)

Thanks!
