I have a 2022 Hyundai Tucson with Carsifi permanently connected to the USB socket. However the USB is powered for 5-7 mins after the vehicle is exited, then the power is removed.
If I stop the car, exit/lock the car, Carsifi LED will turn Red because it cannot find the headunit. I get back into the car in say 4 mins., start it and as you would expect no AA as the LED will remain red. Because power has not been removed from the USB and it seems not to try and connect again.
Although will not happen very often, any thoughts on a workaround?
