I hard wired my radar detector and found that all the fuses appear to be constant, none of the circuits turn off with the car. So must remember to turn it on and off. I had a dash cam but not going to install unless I can find an easy fix. Cheers

Hi All,
Any solution on this?
I'm looking for (+), (-) and Acc to wire a dash cam. A potential location would be the connect into the wiring of the interior lighting and sunroof switch. But, I would need to know the connections. Hope some will find a solution and post.

Even that one is not switched.

For a switched power we should go through the firewall =in the fuse box under the hood. BAD option.

I'll continue to look for options.

Had same problem with my son's mazda3. Ended up using the usb in the centre console and tracking a cable back to the dash cam fitted near the rear view mirror.. temporary until we fine another option.

Agree going through the firewall a no go. The console usb and cigarette lighter receptacle aren't switched on USA model, so also no go here. Still hoping to hear a solution.

That would be good news. Before my last post I went out and plugged my cam into both console usbs and the cigarette and they were all hot without turning the car on. Would just unlocking/entering the car "activate" these?

(y)(y)(y) Thanks! Yes, both the dash usb and the one under arm rest turn off after two minutes and turn back on when you unlock and open the door. The cigarette lighter hole does stay hot. Using the one in the dash will be plenty discrete. Cheers!

That may be a good solution. But it would be nicer to tap into the fuse that powers those usbs rather than into the usb itself. Routing the wire to the internal fuses box is also easier. But, I couldn't locate that fuse in the compartment, seems as an under the hood fuse. But, maybe other fuses in the car itself are powered off after some time as that usbs (possible candidates: F9 or F10 - power windows, F11 - power seat, F18 reverse light....) worth checking. I'll try and test this hypothesis.

Hi, in the mazda3- we tried all fuses in the car (footwell) ....all were or appeared to be unswitched.
just a point though, the front usb is used for Android Auto or Apple car play..

Hi,
Did you test the fuses few minutes after the car is locked? I will try to do this by connecting a DVM to a different fuse each time, lock the car, wait some minutes and check the voltage by looking at the DVM screen through the windshield (without unlocking or entering the car). Maybe one of the fuses is switched off some time after the car is locked. I'll inform on my results.

But from what I remember we tested all..but if you find different let us know... As it was in a mazda3 and things may be slightly different in the cx30..

My experience was also that all the interior fuses were/appeared hot when the car was off. It would be great to find one that powers down after a couple of minutes.

I found this thread on Mazda 3s that seems to confirm the all hot fuses thesis. It has some info on wiring kits that power down if voltage drops and on tapping into the mirror. Since the back usb also operates android auto, I'll probably stick with using the front usb for my dashcam.

the dash camera from amazon quoted is the one we have also the same wiring harness..
tbh i think i will just get a extra long usb cable and tuck it away out of sight, like my son has done..

when i pick the car up i will ask the tech guys at the dealership where they link into for dashcam installs..

Glad I could assist.

I return... is there a link to a dealer With prices for under bumper scuff trays...
I've looked from this side of the pond but can't find anything.

Cheers Steve

I'm not seeing any accessories online except ebay. Also not sure what you mean by "under cover scuff tray" :) Is that what we call a skid plate?
