I was able to find a good buy on the 2015 oem nav unit from a wrecker. I have installed it and pretty much everything works the nav, the steering wheel controlls, the i-mid. Only issue is the volume is quite low when maxed out. At an idle sitting at a light you can hear it but any road noise and you can't. Including pic of the 2015 unit with red marks on the fitting i could connect from the car side. Also a picture of one connector on the car side that doesn't fit into the new unit.
Is there a way to add an amp or something to get more volume?
