  1. I found this to be a very costly fix. MVI makes a harness wire to convert this from 7 inch to 8 inch, the harness Plus reprogramming is nearly $700.00. This, plus the cost of the 8 inch screen and the HMI module puts this conversion and programming of the HMI module puts this in the excess of $2000.00.
  2. Tried to upgrade from 7 inch screen to 8 inch and add navigation. Ordered the screen and radio control but the plugins were different on the screen. I have a 2018 GMC Sierra 1500 Elevation. My radio control has one control knob and the new one has two knobs. I wanted to make sure the screen worked before I ordered the HMI module, anyone else have this problem?
