I couldn't find the normal bluetooth settings either.
My audio worked fine (pandora, spotify, sync 3 radio, etc) before I updated the canbus. As soon as I did that, things went wonky.
Was thinking of doing the update again just to see if something didn't take....
On another note, at night the screen is super bright and I have the brightness all the way down. I noticed the maps (google and waze) don't go to night mode maps like they do on my phone (black background instead of white). Anyone know how to make the screen dim more and get the maps to go to night mode?
