I am relocating my head unit to another place in the car (DD non-Monsoon Premium 6 HU). Upon turning the HU on, it wants a code. This is no problem, since I have my code, but after inputting the code via the 1 2 3 4 buttons, what do I need to do next? The HU just sits with the code on the screen and does nothing. I have attempted to find an "enter" key or something similar, but no luck. Has anyone dealt with this issue before? I tried searching under a few keywords to see if this topic has been addressed before, but no luck.
