Radar detector hardwire "switched v12" not working for me


Dec 14, 2019
San Francisco

I have a 12/2018 build M3 that I just did radar detector hardwire following this tutorial but it looks like my radar detector is not turning off after walking away from the car. Could someone tell me if I am doing something wrong?

Radar detector is connected to power and ON state.
-> I close all doors
-> disable bluetooth on my phone so M3 locks.
-> mirrors fold automatically since key is not near

I expected my radar detector to turn OFF however it continues to remain ON. I have walked away from the car and let it sit for 10 minutes and with bluetooth still disabled on my phone the radar remains on draining power. I did tap into the middle connector as the tutorial stated and it claimed to be a "switched" source that should turn off with the car but doesn't look like it?

I do have SENTRY MODE enabled but my home is an address where it is automatically disabled. I am not sure if this would make a difference or not.... any help is appreciated!
