Fuse #5 (20A) is for the front accessory socket, which is the only load on this circuit. There is a relay that turns it on with accessory or ignition.

Both of #30 and #42 are not used. I don't have details on whether they are always on or with ignition, but you can confirm that with a meter.

I have a Blackvue as well. I used to have a radar detector, but the one I had became effectively useless as it triggered all the time on the blind spot sensors on other vehicles that are so common now.

 

Thanks for confirming.
I’ve had a Uniden R3 and now an R7.
Both were great, with firmware that blocks almost all BSM’s out there currently and auto mute K band after a couple of passes by automatic doors.

 

The R8 is out and came out on top of Car and Driver testing for 2024.

I was going to say it doesn't do laser but the R9 does.
