hi thanks thats the same way i have hidden the wires with the help in post 1
What amp fuse have you used ? also my fuse slots are both currently empty which amp fuse did you use in each one ? also there is two slots in each did you just put one fuse in, in the slot closest to the wire and leave the other slots empty ?

thanks

Refer to posts #31 and #33 by DBOC205.
I used 5A fuse taps.

Btw, finally the day when my dashcam footage will be helpful has come tonight! A shareride driver scratched my fender while he was reversing into a parking spot.

Hi,

I did exactly what the guide in this forum, - this is a dupe post from the main forum,

I have recently got myself a 2019 C63S and and read SO so so many threads on tapping into fuse for the camera. so i have done my research and search on this forum, but Now I have resorted to asking specialist in this forum with the same car.

I have previously owned a M4 and that no was a no brainer to get to work - but now with the C63S Coupe, i have am having so much trouble getting this to work properly ( Both in the TRUNK )

From the trunk, I found that the following thread above,I have a Tester that tells me which has constant power, currently I am using the following

Below I can see there is continuous power and proven to do so, I have tapped into the
However, without fail - 2 hours, the camera completely shuts off, so I go to the TRUNK and test the power, and it still shows it has power to it, so I am at lost now.

Is there an issue with the TRUNK> I noticed lots of people have done it on the driver side... can anyone tell me there setup that works in there C63S 2019 model so I can rule out the possibility of my setup issue?

THanks for your help in advance!

- I am using 15A fuses for both ACC and BATT

At this moment, I need some advise, is my battery faulty? my PMP? I am at loss at the moment

I have the same problem with my 2019 C300 as well that is wired to the boot/trunk. It seems the car battery management system is cutting power for a short time when the battery level drops below around 12.3V. I know it's cutting power because my Mercedes Me adaptor is resetting as well.
I have not found a solution.

I've done many dash cam installs. I currently have a Blackvue DR750S-2CH (front/rear) installed in my W205. I also live in a state with very cold winters (important note).

In order to help you properly we would need to know the brand/model of dash camera you are installing because each dash cam has different settings and features for battery/power management (important note).

Also, do you have or want to use the parking recording feature? (important note).

Does your dash camera have built in battery discharge prevention?

https://dashcamtalk.com/battery-discharge-prevention/

These built-in features will determine how you should connect and power the dash camera, so you don't DRAIN YOUR BATTERY .

I learned that lesson the hard way in cold winter. Now, I use a Cellink B battery backup to power my dash cams and NOT the car battery.

The Cellink B in my car is wired to only fast charge when the car is running and will give me almost 24 hours extended parking recording (*based on settings and camera model)

The new version is called Cellink NEO (it is worth every $$$)

I use trunk fuse #447 (rear 12 volt socket) which only has power in ACC or when the car is running to charge the Cellink B. The dash cam is connected to the Cellink B.

benzdude

Looks like you are using fuse #447 "rear 12 volt socket" and #401 "fuel system".

I would stay away from taping any major fuse that is required for the car to function properly. Especially when driving.

Also, Your dash camera might be shutting down based on its own internal power settings, if it notices the battery voltage level is below a certain point. (not sure)

steves2k

Appreciate the response ! - So sorry to miss the finer details

Yes I would like to achieve a 12V - 12 Hour Parking Recording - I am almost at the point (1 weeks on this to get the CellLink NEO- I previously owned an M4 before and for some reason, that car gave me NO Issue - Simply wiring to a ACC and BATT and it worked like a charm, I assumed the W205 wouldn't be any different haha )

I am using a Power Magic Pro - and a Blackvue DR650S-2CH - Indeed i had the same advice not to plug into the important part of the vechicle ( I am a newb to this, and was advised only to find a continuous power which had happen to be this) so I have updated an using the following

I believe from the diagram W205 - It is 446 and 440? - Basically the following Diagram I followed a guide





at this point I am curious of the following
- Grounding - Does this play a massive role? It is grounded but I am wondering if its in the right location?
- Could my battery be... Useless? ( i just purchased a multimeter to see what my voltage is at - Will the volt go back up when I open the trunk?)
- Apparently the trunk Battery cuts power below 12v which switches off my PMP (could this be a partial charge or an indended Mecedes thing?)
- Faulty PMP ? (I was told this is unlikely)

I am almost at whits ends on this, and searching every possible avenue to get thsi working, Dont want to be paranoid parking in the supermarket hahah - I checked my logs and it seems to be averaging around 2 hours everytime - it switches off the PMP and Camera - its almost like a timed feature.

Thank for you taking the time to read this ! i really appreciate it @BenzDude.

steves2k

So I got the results based on the following test

I left the boot open just to be sure that when opening it, the Volts dont go back up in anyway, ensure the key was no where near the car, and tested it with the voltmeter

When the Camera disconnected ( again at around 2 hours time everytime - Notification below for the past 3 days ) - The volts shows 12V at the battery and at the continuous (BATT) fuse.




I can definitely see it at being 12V - Is it safe to say that the Power Magic Pro could possibly the fault at this point?

benzdude

have you checked your PMP settings?

steves2k

Yes, It set to 12V and 12 Hours at the moment. I was advised my battery is faulty (after 1 year?) from a dashcam forum and that it needed to checked if its charging properly

benzdude

Even if you have the PMP set to 12 hours you may never get 12 hours parking recording out of it.

Your battery may suddenly jump below 12 volts in less than 2 hours and the PMP will shutdown the camera.

Hopefully it's not the battery. After you verify it, you should invest in one of these :


(especially helpful if you have winter season)

I still think it's a bad idea to run it directly off the car battery for parking recording.

BTW. Blackvue cameras are notorious for not having a physical ON/OFF button.

When you park at home (in your garage) how do you shut OFF your camera. ( I had to add an inline power switch)

Hopefully you don't just leave it running.

I pull out - As in just pull out the power cable from the Blackvue - Especially on really hot weathers as I do not want that thing overheating -

I have a new picture, and it shows it runs at 12.45 V which is... pretty good, at this point, I am almost at whits end and likely try get a Cell Battery Pack.

Unless someone else on thsi forum has a working solution It's almost safe to say the battery is OK at this point?

Since this write up was only for a 1-ch device (great write up BTW, thanks), what have folks done with wiring for the 2ch options and routing the power to the trunk fuse box? Do you run the wires on the same side? (is there enough space to fit 2?), or do you run the wires on opposite sides? if you mount your camera to one side of the rearview mirror is it easy to hide cable under the plastic console behind the rearview mirror to get to the other side?

Thanks!

steves2k

For me this was for 2CH, I went from the Driver Seat (Personal preference and was able to fit 2 cables in the roofs) all the way to the back trunk - The solution to have this work correctly is directly tap into the battery since the 2019 (Facelift) since it has cutout at around 20 Minutes.

benzdude

There is only one roof.

Ran both cables down passenger side. Had plenty of space from windshield to b pillar. Behind the b pillar the headliner was tighter so couldn't squeeze wires underneath but luckily the rubber trim hides both pretty well. Initially ran the power cable like the OP but didn't like how it looked next to the speaker and didn't have enough extra cable in the trunk. Ended up running it along the seat and fit better. I did the b124x battery and not a ton of space by the fuse box so that was a surprise. Ended up with the battery in the cubby you can see as soon as you lift the trunk liner. Happy with how it turned out and didn't take terribly long. Just need to get used to the setup.

Dear friends, please help. My car. W205amg C200d: 2015 model I bought an in-car camera viofo a139 parking mode wired car I installed the cables up to the rear mount fuses.Continuous energy and ignition connected energy to which fuse I need to connect.. please respond urgently..

hey guys, I struggle with my GLC43 fuse boxes - I tried first front passenger side fuse box but they all constant power fuses. Looks like the same issue with driver's side fuse box. Is the fuse box in the trunk the only option? or does it have to do with the car itself keeping power for a long time?
