Hello Here I am, I have a station from the avinusa 10.25 site for a BMW E87 NBT (No drive) Since a few days the car radio no longer works impossible to access the main menu the touchscreen no longer responds I have the message "no signal" but in reverse the camera switch very well, I was thinking of Firmware where MCU my impossible to make an update I no longer have access to the menu, is the reset or reboot button does not change anything it always comes back on no signal, had you a solution? Thank you.
