Servus! My dad got a new radio / board computer for his Kia Sorento 2012 diesel at Christmas, today he had it built in and the radio or display plus radio noise does not work (the LEDs already) the old radio is no longer working either, fuses are all good (10A). To that the central locking does not work anymore, driver door does not close everything else, the key is generally not recognized properly so the ignition and engine sometimes do not start where llen (back and forth). Do you have possibilities for testing, solutions or anything else ? Thank you in advance!
