Thanks for the helpful posts, everyone! Just finished installing my Viofo A139 Pro 2 channel I got from Blackboxmycar. I used the fuses as mentioned on page 2 using the Viofo HK3-C Hardwire kit. Works perfectly including the parking mode! I used the T20 bolt that's holding up the glovebox instead of the airbag which is a few inches to the left of that bolt. Still works and don't need to touch the airbag at all.

It's a soft material, you just have to kind of massage it out straight. I had the same issue but with some effort I got it back to where it has zero gap.

Smile Use fuse 74 & 38 on the G20’s fuse box

Gonna jump in here as I just successfully hard wire my VIOFO A129 Pro dash cam to the fuse box located in drivers footwell (right hand drive U.K model)
I tapped into fuse No:74 which protects the USB socket in the car as my ACC accessory connection (10amp mini fuse) then after lots of false hope connections I stumbled across fuse slot No:38 (5amp mini fuse) which was empty on my car but it had power going to it , this I used for my BAT Battery connection which has constant power therefore allowing me to access the ‘Parking Mode ‘ feature on my camera.
I had to purchase the VIOFO HK-3-c hardwire kit as well as mini fuse taps/fuses from Amazon as VIOFO as well as some other companies DO NOT provide the extra parts that in my opinion ought to come in the box. That way newbies like me can have a much smoother easier experience in installing a plug & play gadget.
The hardwire kit for me was essential as it comes with a car battery protector so the cam doesn’t drain my rather expensive car battery.
Been a week now & everything is working fine for me.
Hope this post helps many others ,
Happy driving , peace! ☮️

Is it wise to disconnect the battery when fitting both a front and rear dashcam on the G20? I'm due to be installing a Nextbase 522 bundle in the next few days using power from the ODB port.

I did want to purchase the BMW Advanced Eye 3 pro kit but the local dealer would not supply this saying it had to be fitted by themselves. Not sure if its worth the extra £100 for this either as I got the Nextbase bundle (with memory card) and ODB hard wire kit for £225.

The battery is in the boot. Use that as always on.

I hardwired my Viofo A129 Pro Duo directly to the car battery and rear fuse box. This requires soldering/crimping to extend the hardwire kit.
I used this wire from Amazon:

20AWG UL2464 Power Cable LED Red & Black & Yellow 3 Conductors tinned Copper (2464-20AWG-3C- 25ft)

Red to battery + terminal
Black to battery - terminal
Yellow to fuse tap to Rear fuse box F214

Thanks to previous posters who shared fuse diagrams. I was following the CarEye instructions which didn’t work for the Viofo A129, but all good now that F214 worked.

Good luck!

Plenty of great helpful info here. Am going to use Fuse 59 as ACC for my dash cam but have a question regarding the fuse tap. Which side of the fuse (in the box) is the power side and which is the device side? Want to make sure I am orienting the fuse tap the correct way as it looks like in some of the photos people have them going both ways - which in some cases is incorrect. Thanks!

I purchased fuse taps from Amazon
https://www.amazon.ca/gp/product/B078T7JSFD/ref=ppx_yo_dt_b_asin_title_o01_s00?ie=UTF8&psc=1

My Fuse Assignments are:

*For BATT - Fuse 38 (Empty) - Assigned to NFC Charging
->Slotted a 5A & 3A fuse to the fuse tap.

*For ACC - Fuse 71 - (Occupied) - Assigned to Ambient Lighting
->Slotted the existing 5A fuse and added the 3A fuse to the fuse tap

*For GROUND - Drilled a small hole the size of a #12 bolt into the metal bracket which holds the Airbag (See image). There is a screw and nut which holds one side of the airbag to the bracket, but I discovered you can't take the screw off or get enough space in between to slip the ground wire in. No other metal screws in the vicinity so drilling was my only option.

*Set the limiter to 12.2v

My reasons for going this route. If you can understand fuse taps and which side is the LOAD and DRAW sides then you will have a better understanding of the direction the fuse taps need to be plugged in and which direction the fuses themselves need to be plugged in to prevent blowing the fuses. Since the fuse box presents some slotting challenges, I worked with what was available.

Fuse 38 was empty and only assigned to one item in the car (NFC Charging).
Fuse 71, although occupied, was only assigned to one item in the car (ambient lighting). It also provided enough distance [...]
hey i followed your instructions to hardwire my viofo dashcam in my m340i. the only thing is for the fuse that goes into 38, i only put a fuse tap on the slot furthest away from the prongs, and i plugged it in the direction you had it in the pictures.
also, does it matter which slot the bat/acc cables go into?

Went through this and had some issues (turned out defective Viofo softwares which I resolved). But in my testing, I managed to try a few fuses and they all checked out fine.

38 has no fuse, and needs no fuse on the top of the fuse tap (so just need the 5A for the dash cam). 38 is live, all the time. So you need to use BATT there if you want to enable parking mode.

71 provides power when ignition is on. ACC must be connected to a fuse that cuts for when the engine is off (well ~10 mins after in our cars).

You could mess around with other fuses (I ended up with 25 for BATT and 59 for ACC). But you want to avoid any critical fuses (airbags, safety, etc)

If yours is up and running as you’d like, I’d leave it alone.

It's currently up and running now. But this is the second A119 V3 pro dashcam i've gone through. My other one somehow bricked and would not turn on anymore. Not sure if it was due to the wiring potentially shorting the dashcam or what. But I got a replacement and it's currently working well (at least for the 2 drives I've been on so far with it lol). I may just double check to make sure the proper wires (acc/bat) are in the right fuses. Other than that I think it should be good.

Is there any positive answer about using the OBD port to power a dashcam?

Some say it will set off the alarm, other say it wont on later models of bmw, other say coding is required, some say it will only set off the alarm if you transmit anything other than power etc?

I have an M340d with the Garmin constant power OBD adapter/cable running a Garmin Mini 3 (front) and Garmin Mini 2 (rear).

Adapter set to run parking mode for 12 hours after locking car. Been running for 3 weeks now and had no alarms or battery warnings etc.

I had grabbed a cheapy OBD port power adapter and used it for a while but just didn't feel right about it. Kinda like plugging in a mysterious USB connector not know if it's doing something else... The Garmin noted here is I'm sure decent quality and safer to go with if you're going to run one.

I eneded up connecting into fuse 59 but have an odd situation where if auto start/stop is on and the car turns off the power to that fuse turns off. Car starts, power returns. If I turn off auto s/s, which I always do (damn you Bimmercode for not figuring out the fix! ), then no problems. Anyone else have this problem or did I perhaps tap into the wrong fuse?
