2009 Mini stock stereo with boost CD player doesn't turn on / no display when pressing the power button, but the CD unit will accept and eject discs. Passenger side fuse box - fuse F23 checks ok, when I re-install the fuse, I can hear the CD unit energize. When I turn on my lights, the stereo and CD back lights illuminate

 

Wondering if the push function of the switch is shot.

 

If the push button is bad... any suggestions how to test/troubleshoot? A replacement radio/speed cluster listing on E-bay is easy $180

 

Why do you mention "radio/speed cluster"? Are you sure you have an '06? The radio is not integrated in '06 and replacements start at $30 on eBay.

 

Apologizes.. 2009 not 2006. I just finish editing the post

 

Update- I wanted to see/hear if when I insert a disc that I could hear the CD unit mechanically try to read it. Unfortunately once I insert the disc I couldn't hear any type of sound/movement inside. However I accidently inserted the disc upside down and strangely it spit it out. Is that a sign that the stereo unit is somehow working?

I haven tried to test the 2 rear fuses considering the CD unit is powered up and its a pain in the butt to remove the stereo unit

 

The rear fuse checked ok..So I decided to buy a used CD unit on E-bay for about $80 (no speedometer) , there was a volume circuit board for $30, but didn't want to take the chance if it wasn't a power button issue. Not fun trying to disconnect/removing all them wire connector harness in the back area. (they make it look so easy on YouTube) But over all a person will normal skills using hand tools should take around 4 hours to remove and replace the stereo unit and panels. Once I connected the CD/stereo wire harness, I could hear the CD unit energize. Then when I turned on the ignition.. all the stereo/lower speedometer display and sounds awoke like magic! So the fix was due to a bad CD/stereo head unit.

One thing I didn't realize is and its a good troubleshooting point is with a normal working day to day Mini Cooper.. when you put your key in the ignition, there are normal status sounds such as when you open a door open or leave the hatch open. So If you don't hear any of those sounds.. you most likely have a bad stereo unit. If your able to slide a disc into the CD unit and your stereo don't still don't wanna turn on; you know all stereo fuses are good.
