I have a similar problem. I have a start screen only. How to restore this radio to life.
Hi,
I have a Kenwood DNX 5280BT black screen.
Can someone help me with pre-boot mode and firmware flash for it.
I can't find the pre-boot switch on pcb board.
I try to connect to PC via USB port but it dosn't recognized.
Thanks
Stan
