Timer for power GPS when the PC and out

Automatic switch VGA-AV and AV-VGA with input from the lamp reverse of the car(only for Lilliput) connect in parallel to the switch original for rear cam use

Automatic fixed lighting of the blue leds of the keys when the lights of the car(only for Lilliput) connect to the pin 8 and 12 of the Lilliput

UPDATE PHOTO NEW VERSION OF THE HARDWARE

Edit: ALL the Input -Output in the new board is optoisolated.

For all guys:
If you have the Lilliput monitor (7" TS) I ask you to make a test:

Turn on the PC and also the Lilliput, tries to push the button AV to manually go to AV1 (the PC has to be in initial phase of boot) and tell me if Suffered the Lilli, only in this condition (first 5/8 second max of operation) succeeds in commuting from VGA in AV1 or no.
Do you him to know in this thread.

Thanks

I assume the AV/VGA Lilliput switching can get out of sync if you swap the modes externally via the button and/or remote, right?

The Pic simulates the input on the original button of switch of the lilliput VGA-AV.

I am sorry but I didn't get it. Will this device switch the VGA to AV1 and 2 on a lilliput automatically hen the reverse light is on and then back to VGA when it is off?

I read the other threads and downloaded the project. Unfortunately it is way over my head. Will you build and and sell one to me? I only need it to switch the lilliput. Thanks.
