Shift into reverse gear, tap the screen, select “Trajectory Style,” then tap the text for “Continuous Click Style 1” to bring up the adjustment menu.

dcooksey

I only have brightness, saturation, contrast adjustments plus buttons for 'restore defaults' or 'radar settings
I have the trajectory lines disabled. The lines you can see are from the factory camera. The entire image is stretched.

Click here repeatedly and try it out.

That only controls the trajectory lines NOT the camera image. At the moment I am only seeing 1/4 of thge camera image on my screen. The camera image needs to be scaled to fit the screen resolution

All you need to do is click here continuously (Style 1)
and the menu you need will pop up.

Hello, you need to use the AUX app to check whether the original vehicle's system UI is fully displayed. If not, you need to change the original vehicle's screen size and resolution in "Vehicle Information" > "Vehicle Settings."
The reverse image will only display fully if the original vehicle's system UI is fully displayed (they are on the same video signal).

dcooksey

dudu-lai the Aux app says no video signal,
The vehicle details app says not supported
Use legacy interface
The legacy interface has adjustments for AHD resolution and scaling but they do not work. I cannot change the values

dcooksey

Ok, I found this menu. Not very intuitive! It just controls the display window size. Not the scaling

I found a random photo of the wiring harness for reference. On the RZ-AUDI30 CANBUS box, there are two RCA video jacks. One connects to the DUDU's Zone A video input (AUX application), and the other connects to the DUDU's Zone F reverse video input (displays when reverse gear is engaged). Please check.

If you do not connect the C connector, the value cannot be changed.

dcooksey

dudu-lai Thank you , I will check

dcooksey

dudu-lai so, my problem was the c connector. It was connected but one wire was loose. I only have one rca video connector, not two coming from the interface module.
My reverse camera is now functioning correctly although I am not happy with the image quality. It is not as good as with original factory screen

dcooksey OEM cameras have lower resolution. If you need higher definition images, it is recommended to install an AHD camera.

dcooksey

dudu-lai Quality not as good as with OEM screen. Same camera, aftermarket screen , quality reduced.

dcooksey A low-resolution camera, when displayed on a high-resolution screen, will have a reduced quality.
