[FYT Android Head Units] mastrv:
Here are some comments/updates on the settings.

Many options are common on FYT models. I have a CC2 but many of these functions are similar on the CC3. If anything is incorrect, please confirm and update with corrections.

Some videos showing functions can be found on youtube and also on the TEyes site. Not all options will apply to all models/manufacturers:

TEYES CC3

Note that these were correct at one point. With updated/newer firmware, some of the shown items may no longer be correct or apply.

- LOUD

Maybe this is related to those sound settings that change the "loudness" of the sound, as described here:

Loudness compensation - Wikipedia

en.wikipedia.org

Shown in this video at about 1:06:

It says it enhances the treble and bass when on, which I believe is similar to the wikipedia description.

- Press any key to start

Referring to the touch buttons on the left. This video explains it. Shows how this works starting at 35 seconds:

- Original Car Agreement

I believe this section changes depending on what your vehicle and CANBUS supports.

For example, if your A/C information does not go through the CANBUS, the A/C setting may not appear in this section.

- Automatic start and stop

I believe it is useful for cars that have automatic stop and start. Newer cars turn off engine when they get to a red stop light, for example. I think this option keeps the screen on for a short amount of time such as when automatic start/stop engages. I keep this on so that when I turn off my car, the head unit stays on for a short period of time. If I then

want to listen to the radio I then put it into the accessory position.

- Static Track

I believe this is for seeing reverse parking lines that don't move and are static. Useful if the dynamic tracking lines are not correct or prefer static ones.

- Rear door exchange

Similar to Drivers door position...swaps the rear doors left to right and right to left. Not sure why this is important...maybe for DSP or volume balance, etc if the wiring was swapped.

- Protocol Print

When on, this displays the CANBUS messages overlayed on the screen

NOTES

=====

- VPN

previously, you were prompted to set a pin code/security before setting up a VPN. However, once the pin was set, could not unset it and could not enter it and have it recognized

- AMP ON/OFF

In previous head units, this also controlled the fan if one was installed. Later a separate fan control was added

- Power Conditioning

I consider this as absolute sound and then other sound settings are based on that. So, what I did was figure out the volume that I wanted to normally listen at. I normally listen to Poweramp from about 8 at the low end to about 12 or 15 and when I really want to pump up the volume, I put it to anywhere from 20 to 25. The upper limit of volume setting is 30. At all of those levels, there is no clipping and sound does not get cut.

So, figure out your normal volume and then adjust the power conditioning so that the volume fits and so that there is no clipping.

- Sound reduction when reversing

This works with the previous "Mute audio when reversing". The Mute audio settings must be on for this setting to have effect. This determines how much the audio is muted or reduced when in reverse when Mute audio for reverse is on. This video at about 3:20 shows this and the Mute when reversing settings:

- Sound mixing scale

Note that many of the navigation software also have a sound volume setting. For example, I use Waze and it allows me to increase or decrease Waze sound. If the sound mixing scale doesn't quite set the relative volumes well enough, then check your navigation software to adjust the sound further.

- Antenna normally on

Some cars require a constant 12V power supply for the antenna. I believe the VW cars do this...may include Audi and Porsche.
