I have a 2013 W204 C63 and am looking to add Android Auto to the car, probably the Integrated Automotive module. Haven't seen anything like a "how to guide" on installing these but I presume there'll be at least some basic instructions included with the device. Just wondering, anyone who's done this on a W204 that can say where they located the module, any tips for routing cables etc., removing the dash panels etc. to get access, anything like that?
