I am thinking of setting up a Raspberry Pi 4 with an SDR and OP25 in my 2019 Ford Ranger to listen to a P25 system. I would use the Bluetooth to send audio to the Ford Sync audio system. I would power it via a usb charger in one the truck's 12V ports. The Pi would, of course, be set up to start OP25 on bootup so it could be headless. My question is this: The truck's 12V ports are on only with the ignition. Would the constant killing of power and rebooting every time I start or stop the truck have any adverse effect on the Pi or corrupt the SD card?
