Please release a 2K DVR app for universal Android head units.

I already searched Telegram. When I looked for "cardvr," it seems that version 335_0.0.17_F is the latest one available, and I couldn't find 335.0.0.18_F shared by Chubaka885. Thank you.

The HD DVR app worked stably with the DUDU 2K DVR camera, but the ADAS warning sound was only a BEEP. Since the DVR 2K app offers both a BEEP and voice alerts for ADAS warnings, I had been hoping to use the DVR 2K app instead.

Up until now, I had been enabling the ADAS functionality in the HD DVR app to display ADAS on the DVR 2K app. However, enabling the ADAS function directly in the DVR 2K app caused frequent crashes, making it impractical to use.

I suspected that the DVR 2K app was missing some backend functionality necessary for it to operate on a generic Android head unit, and it seems that the missing piece was the "DUDU DVR Service."

When I installed the DUDU DVR Service, the HD DVR app was automatically uninstalled, which suggests that the service includes alternative functionality to replace the HD DVR app. If this assumption is correct, I would like the DUDU DVR Service app to be bundled with the camera for users of generic head units that are not DUDU head units.

Since I have not driven with the DUDU DVR Service installed yet, I have not confirmed whether the ADAS function in the DVR 2K app now operates stably and correctly. However, during ADAS calibration, the crosshair now displays correctly at the center of the screen, so I am optimistic.

Thank you, YAOXILONG and Chubaka885.
I will start using the files you have provided from tomorrow onwards.

I am reporting the result of installing the DUDU DVR Service to enable full functionality of the DUDUAUTO 2K DVR on a general Android head unit, which is not running DUDU OS, and the DVR 2K app.

All functions, including ADAS, worked stably and properly. When I selected the voice alert option in the DVR 2K app’s ADAS, it started to give voice warnings in my country’s language correctly. My head unit uses Google’s TTS for this. Since I have never used Toppal, I am not sure whether voice alerts will work with Toppal.

Additionally, the coordinates and speed, which had never displayed anything other than 0 before, are now being displayed correctly. These coordinates and speed are also correctly included in the recordings on the TF card of the camera itself.

I just tried the firmware FW_CarDvr_335_0.0.18_F_DUDUAUTO.
The update instructions mentioned checking the LED blinking pattern, but I couldn't find where the LED is located on the DUDUAUTO 2K DVR device.
For now, I wrote the firmware file to a microSD card, inserted it into the DUDUAUTO 2K DVR, powered it on, and waited for one minute before checking.
I confirmed that the version number was updated.
However, I am not sure what changes were made. I would like to have a changelog.
Thank you.

I tried uploading a video to this forum, but even smaller files than the displayed upload limit are actually rejected.

The voice is in Japanese.

In the DVR 2K app, the Lane Departure, Forward Collision, and Front Car Start alerts all worked with proper voice notifications.
When the sensitivity is set to High, there are so many warnings that it becomes almost annoyingly noisy.

I don't know how to fix the bug in the universal version of the app where "72 km/h" continuously appears at the top of the screen. However, it seems possible to hide the speed display by touching the screen and changing the display order so that the camera video layer is placed above the speed display layer.

The coordinates and speed in the lower left corner of the screen are occasionally displayed correctly, but most of the time, they show as 0. I don't know how to fix this either.

There were some inaccuracies in my previous reports in this thread regarding the 2K DVR app.
The ADAS voice is not generated using TTS but is instead played as WAV files recorded for each language. The Japanese voice in the 2K DVR app was most likely a recording of Google's TTS. Since it sounded identical to the Japanese voice of Google TTS on my head unit, I mistakenly assumed that the 2K DVR app was using TTS for speech.

The DUDU DVR Service was also included in the 2K DVR app. It seems that the issue stemmed from the fact that it was not installed correctly when I first installed the 2K DVR app. My head unit is made by a different company, not DUDU. However, the reason AR ADAS functioned on the 2K DVR app despite this was likely because the app was not properly installed. After repeatedly reinstalling the 2K DVR app, I was no longer able to display AR ADAS. It is probably correct that AR ADAS does not function in non-DUDU OS environments due to the hardware/software environment check within the 2K DVR app, but this is unfortunate for me.
