Hello you love, I have the Clarion Radio NX501E in my KIA. The touchscreen is not so clear anymore, but you can only see that when the light falls on it. Now the car was for repair (recall from KIA). Since the Radio Total spins. The radio stations are no longer played, and you can no longer tap on a transmitter, it always jumps back and forth and always beeps. Although it is not touched. Does someone know each other and could help me? Or is the Ra I’d be grateful for Hilde. LG Jutta
