Correkt wire but lost settings

[Harry]

Hi i have the problem that my radio lost all settings but only after several hours.
7" 11-C0255
with mtcb-kdl 6 v2.81
Rk3188 with 1024x600

Yellow is direkt on the bat +, black is on Ground -, red and illumination is on ignition

When I start the radio it turns on and of with ignition and it says shut down if I turn on the radio after some minutes it is direkt without booting on the homescreen and all is fine but after some hours it starts first if I push the power button and it lost all settings and my Spotify downloads are gone clock is 0:00.

What can I do?

Hi there
Sorry for replying you late due to the holiday massive mail volume. Hope the reply still can help you!
I think it must be something wrong with the power supply for the yellow BAT wire. Could you mind check about that? Cause only the yellow wire lost power will cause the radio lost settings.
Regards!
