I removed the head unit to install the relay, and noticed that in the provided wiring loom pin 7 in car's side goes to pin 4 in Pumpkin side, and pin 4 in car's side goes to pin 7 in Pumpkin's side. Obviously I can get fast boot to work as designed without additional relay if I change these wires.

Yep, now I have fast boot, and the "ACC on" setting works as it is designed. Now I just need to decide, if I want to have power on for certain time to listen to the music without ignition power on.

dnapekko are you saying you switched the yellow and red wires and that fixed the problem of the radio cold booting every time? I contacted Pumpkin about it and they said that the Android 10 version is designed to cold boot every time. It's not a huge problem but I wish it would fast boot like my Android 9 one did.

I do not remember the colours, but the wires crossed from pin 7 to 4, and vice versa. My Android is not 10, though. If Pumpkin has changed the system to cold boot every time, it is very silly decision. I already considered a time delay relay to solve the very annoying cold boot issue. Next step would have been to change the player to another brand
