Hi guys
I've changed my car radio and lost a feature that was on the factory unit.
Normally after switching off the car, the radio will stay on for about 5mins or until the drivers door is opened and switch off at this point.
The current radio switches off immediately when the ignition is switched off.
As the unit doesn't do this, I want to design something that can replicate this.
For the timer part, could I use a timer relay like this (https://www.aliexpress.com/item/4000918306923.html)? but this only has a 10sec timer. I guess I would have the ignition as controller and always live on the other side.
How do I incorporate the door switch so if its on timer, it'll immediately switch off?
Or is there a better/ combination circuit I need?
