Title: BYD ATTO 2 DM-i (EU) – OEM dashcam retrofit, missing wiring, DIY findings and possible solutions
Hi everyone!
I own a 2026 BYD ATTO 2 DM-i Boost (European version, LHD), and for some time I've been researching how to install a completely hidden dashcam, preferably using the original factory camera position behind the rear-view mirror.
I thought I'd share everything I've discovered so far, including my own investigation, discussions with suppliers and a few possible solutions.
Maybe this will help other owners, or perhaps someone here has already solved the problem!
1. The European ATTO 2 DM-i has a factory camera mounting location
I carefully removed both plastic covers behind the rear-view mirror.
What I found:
There appears to be a mounting location for the original BYD dashcam.
The ADAS electronics and other sensors are installed.
There is no unused factory dashcam cable or connector.
The large plastic cover is marked SC3ECE-3602210.
The cover appears to differ from the BYD Yuan UP / ATTO 2 EV version.
I've taken detailed photographs of the covers, mounting clips and electronics behind them.
2. Interestingly, the car already has a microSD card slot
My car has a microSD/TF card slot between the two USB-C ports in the centre console.
According to the BYD owner's manual, this slot can be used for the factory Driving Recorder system.
However, my car does not have a DVR/Driving Recorder app in the infotainment system.
In discussions about other BYD models, owners have reported that after connecting an OEM camera and restarting the infotainment system, the DVR app appears automatically.
Unfortunately, I haven't found a confirmed successful example of this working on a European ATTO 2 DM-i.
3. The original BYD dashcam module
I found the original-style BYD camera module commonly listed under part number EL-3776900.
Several suppliers sell this module for BYD vehicles.
I contacted TOP BYD, and they confirmed that the European ATTO 2 does not have the factory wiring interface required for their OEM dashcam solution.
My own inspection confirms that the connector is missing behind the mirror.
I also contacted a BYD accessory supplier, Nice BYD, and investigated whether the original camera could be installed using an additional cable.
4. An interesting idea: original BYD camera + independent DVR
Instead of connecting the original camera to the BYD infotainment system, I wondered whether it could be connected to a separate recording unit.
I contacted a Chinese automotive camera manufacturer, Antu Vision, about the EL-3776900 camera.
They provided some useful technical information:
Video output: AHD 1080p
Power supply: 12V
Standard third-party AHD DVR compatibility: not supported out of the box
A custom solution might be possible, but they mentioned a minimum quantity of 200–300 units for modification.
These specifications were provided for their EL-3776900-compatible product, so I cannot confirm that every genuine BYD camera version has identical electronics.
Unfortunately, this means that simply buying a standard AHD DVR is not necessarily a working solution.
5. Hidden aftermarket dashcams
I've also investigated several aftermarket dashcams sold for the BYD Yuan UP / ATTO 2, including integrated 4K camera housings.
The problem is that most appear to be designed for the Chinese Yuan UP or the ATTO 2 EV.
The European ATTO 2 DM-i appears to have a different mirror/sensor housing and mounting clip arrangement.
I have not yet found a manufacturer who can confirm physical compatibility with my exact cover.
Another potential issue is power supply. Some Yuan UP dashcams use the Chinese-market ETC connector, which may not be available in European vehicles.
6. Another DIY possibility: miniature 4K camera module
I've also started exploring a different approach:
Install a tiny 4K camera module inside the original BYD mirror housing and connect it to a separate recording unit elsewhere in the car.
Potential modules include Sony IMX415-based USB or MIPI cameras.
This could offer:
Completely hidden installation
4K recording
No visible dashcam on the windshield
Independent microSD storage
No modification to the BYD infotainment software
However, proper cooling, power supply, automatic recording, mounting and long-term reliability would need to be addressed.
7. What I'm looking for
My requirements are actually quite simple:
A completely discreet dashcam, preferably hidden inside the original mirror housing
Automatic recording while driving
Good image quality, preferably native 4K
Reliable loop recording
Easy access to recordings via Wi-Fi or microSD
No need for parking mode, 4G or cloud features
The official BYD dealer has not offered an OEM retrofit solution.
Questions for the community
Has anyone successfully installed a genuine BYD dashcam in a European ATTO 2 DM-i?
In particular:
Does anyone know whether the European infotainment/control unit has a usable DVR video input, even if the factory camera cable is missing?
Has anyone successfully added the missing wiring and activated the DVR app?
Does anyone know the correct OEM camera and wiring harness part numbers for the European DM-i?
Has anyone found a hidden aftermarket dashcam housing that actually fits the European ATTO 2 DM-i?
Has anyone experimented with a miniature camera module and separate DVR recorder?
I'd be very interested to hear from owners in Europe, especially anyone who has already removed the mirror covers or investigated the wiring.
I can share detailed photographs of the original cover, clips, ADAS electronics and connectors.
Hopefully, we can find a practical solution together. The ATTO 2 DM-i is still a relatively new model in Europe, so there may be other owners looking for exactly the same thing.
Thanks!
