I read somewhere that 2016 2500HD's with 8inch screens have the android auto. So I was trying to connect my phone, and couldn't. So I called gm for assistance and they said it wasn't installed on my truck and the dealer was given a 400 credit because of this. I could be mistaken, but I am pretty sure I read that's it is a free software update that was available from the dealer. I asked the gm rep and she said I would have to talk to the dealership and it was up to them. Has anyone else done this, or had any issues when asking for the free software update?
