Ordered my new HU and I am doing all my homework for installing. Can someone please tell me how to remove the OEM NAV button plate so I can get to the two screws underneath? I have read the how-to's, done searches but no one gives a solid answer, and the how-to's are w/out NAV. The NAV isn't something I want to break trying to remove. Thanks for the help.

 

I used a butter knife. Gently wedge it in the gap between the dash and the panel and push the panel up. It snaps right in and will pop out off of two tabs.
