Hello everyone, in our new Micra K13 NTEC, the radio unit has already gone crazy twice. This looks like this: vehicle shut down in the evening – everything is fine. In the morning already before boarding: the screen is black, above a font in English: “Insert an updateable medium. ” Then 60 sec are counted down, the screen becomes completely black, after that the game starts from the beginning. Meanwhile, the unit reacts to no keystroke, it goes on like this, no matter if the ignition key is inside or outside. They’ve been in the workshop twice – they’ve never seen it before. In any case, the software is up-to-date in the device. They then disconnect the radio from the current for a while, after that everything is normal again. Unfortunately, this doesn’t stop for sure. Does anyone know what this could be or has experienced before?? Thank you, R70
