Put in a red start button today. See below for pictorial...

This is a $7 one from AliExpress. I am sure these are that same ones selling for much more from our favorite vendors. Safer to buy it from a trusted vendor in case of problems and timely support but these work well.

Paint can removal tool is my favorite trim tool of all time. This panel has 4 posts. Top left and right, and bottom left and right. Hook the top and pull it free

lol screw that, I'll just throw you one. Besides I need to still get this stereo back together and do some audio tuning with you. Just still fighting my car on hardware and some tuning.

Nice install and very helpful instructions on how to get the dash apart. That isnt always easy to figure out in different vehicle

Please confirm that on a 2011 Z4 E89, there is no possibility of changing this button without taking out the dash . Thank you .
