Digging up a slightly old thread. I'm trying to hard-wire my radar detector and cannot get any power from this fuse panel. In my 2018 I just used the mirror tap and it worked fine, but I cannot get the panel off and I'm not going to risk breaking it. So I figured I'd try this fuse panel. Easy to get to, but I just cannot get any power. I've tried my setup in my other vehicle and it works fine so it's not a faulty fuse tap or power cable. I tried both slots mentioned above and nothing. I even pulled one of the existing fuses and tried to piggyback off that. Still nothing.
Any suggestions? Might my fuse tap not be long enough? Again, it worked fine in my wife's car, but it's a MB.
This is for a 2022 F90 M5C.
