Guide: 2nd Generation CX-9: Dashcam installation

Hi All,

Seeking the experts here for a CX9 2019.
Looking to install a Viofo HK3 3 wire for my dash cam. This hardwire kit comes with 3 wires to constant fuse, ACC ignition fuse and ground. Referring to the diagram below under fuse block left side, I will install the ACC ignition to either position 3, 14 or 15. I want to confirm which position is the safest for the constant fuse.


Apologies if this was mentioned in the thread. It didnt catch my eye.
Many thanks in advance.

I just bought one of those inviscord type adapters specifically made for Mazda Frameless mirrors ( SimpleUSBPort Dashcam Adapter for Mazda Frameless https://www.amazon.com/dp/B082ZSFQ8C/?tag=m20b7-20 )

Has anyone installed it? From my initial look I didn’t find the port to remove from the back of the mirror. Do I need to remove the mirror or trim to gain access to the port?

thanks!

Hey Shim, I'm not 100% sure, but I think 3 or 14 would be fine. Hopefully someone else with more experience can chime in.

That vendor is actually a member and authorized merchant here (@K3vonn). With the frameless mirror, you'd have to take the black plastic cover off of the housing attached to the windshield. See posts #36 and #38 by @petesamprs on page 2 of this thread.

@sm1ke Thank you! Even though I read through this thread a couple times I totally forgot that post 38 was frameless mirror.

Thanks sm1ke. I ended up buying a circuit tester and quite a few of the fuses had power running to it with the engine off. Yes 3 was one of them. I didnt test 14 as I had my ACC fuse plugged in 15 which covered fuse 14. My first attempt/option was fuse 15 and it worked as ACC. So I assumed all the 'outlet' fuses worked the same way.

I noticed the sunroof fuse had constant power when the engine was off. I thought if it had constant power, the sunroof would operate. However, it doesnt open when you press it. Scratching my head on this one.

Alright, finally got mine installed. For anyone looking for instructions on how to open the enclosure behind frameless mirror follow post #80. Thanks a bunch to @amalraj for immaculate instructions, you truly made installation a no brainer!

Here are some pictures. I bought a 9” USB A to USB mini cable which turned out to be perfect length.

The SimpleUSB port took the guess work out and made it incredibly “Simple”. However, I wish the wires were a bit longer. I was able to stuff everything in the enclosure, slightly longer cable would have allowed me to properly snug them instead of just stuff them inside while trying to close the cover.

This has been a fantastic thread, full of information. Thank you all. Wanted to clarify before pulling the trigger on my own for my new 2019 CX-9.

If I go with the: SimpleUSBPort Mirror to Dashcam Adapter (10-pin Type A, Nissan/Infiniti/Mazda) and then run the A129 using the Advanced Buffered Parking Mode it will run off the CX-9 battery all the time correct? Thereby capturing any impact that triggers the G-sensor?

While I don't want it draining my battery, or it being triggered all the time in my underground, but rather more so when we're out and about in parking lots shopping. Not sure about the draw on the battery with this feature on? @sm1ke is yours configured this way?

@604Mazda Yes, the equipment you listed will have the camera running off of the CX-9's battery all the time. I park in a garage, so when I'm home for the evening I shift the camera off of it's base to turn it off and prevent battery drain. When I'm out, depending on how long I'll be away from the car, I will switch to the Parking Mode. I also have the camera set to turn off the LCD display after 3 mins. Draw on the battery should be a little lower since the camera isn't actively writing to the card at all times. Typically, if I leave the car with the camera in the normal recording mode, the battery drains in 3-4 days and I might need to jump-start it. This happened once when I went away for work, which is why I always turn the camera off when I get home now.

One other note: be sure to turn off Parking Mode/Motion Detection before you start driving. If you don't, the camera may automatically stop recording (not sure why this is).
 
Hi All,

I finally got a chance to install the Viofo HK3 3 wire kit. Thought I would share my install with everyone incase you decide to hardwire your dashcam. Apologies if this has been documented before. This is for RHD where the fuse box is on the left hand side.

So after determining which fuse to use for acc and battery, I have concluded the best options to use (and thanks to sm1ke) fuse 3 for battery and fuse 15 for ACC.

For fuse 3 battery, I used a micro fuse tap for best fitment. It will push all the way in just like the fuses on the car. The hot side for the wire tap is on the outer side, so insert your fuse tap with the positive to the hot side.
For fuse 15 ACC, I used a mini fuse tap due to a piece of plastic trim on the fuse box preventing from the fuse tap from completely pushing in. The hot side of the fuse is on the inner side, so insert your fuse tap with the positive on the hot side.
Ground the wire to a bolt directly under the footwell (you cant miss it).

Cable tie and neatly store away the wires and unit.

Select your desired voltage cutoff. I set mine to 12.4V for now.

Now the test is to see if this unit cuts power overnight. I assume it will keep charging my dash cam continuously even in sleep mode then fingerscrossed it will cut at 12.4V.

Hope this helps
Shim
