I went in to pick up a new head unit from CarToys today (AVIC Z120BT). Long story short they started giving me some story about that since there is something electronic in the parking brake, they can't just hook up the wire since they claimed they shorted out 3 computers in the car doing something similar with 2011 Subarus, and so to install it they would either need to install a remote start or something to create a new ground. I'm not particularly fluent in all of this, but something seemed fishy. Does anyone know if these guys are full of it? I added up the part sheet they drew up and one with Amazon (minus the bogus ground kit) and including the "free install" they were $600 up on Amazon.
