Truck apps on instrument panel problems
Well....ya got me curious!!
I just went out and turned on the ignition without starting the engine, and when I went to that app I had just what your picture shows in post# 1 - no lines, and no indication of steering angle.
I thought it would come back to normal when I started the engine - but no.
I backed out of the driveway and drove down to the end of my street - and when I got to about 12-15 mph the lines appeared, and when I turned the steering wheel the wheels on the display moved and the steering angle appeared.
So....just drive faster than about 12-15 mph and I bet your display will start showing steering angle.
