Need help! I have read through several posts and I am still having troubles determining an appropriate power source for hardwiring my radar detector. I have a 2009 528xi. I removed the overhead console (with the sunroof switch, SOS, and airbag indicator) and am not sure where to tap into for power/ground. I have seen several posts on this forum website but none apply to my car. I have attached a photo of how my overhead console looks like. Any guidance would be greatly appreciated. Thanks.

You need to buy a 12 volt tester, attach the ground wire to something metal and touch the silver wire connectors at the end of the wires to see which has juice that turns off when you remove the key.
I went and bought an Escort radar detector that runs on batteries. 100X less aggravation.
