It looks like the radio may be serviced by replacement only, I see no service procedure for a bulb.
On the HUD, it is powered by the IP-IGN fuse in the instrument panel fuse block. I am assuming you have checked the power switch and dimming switch for the HUD, and still have no operation. Power from the fuse goes to the switch on the pink wire pin A, and ground is black pin G. It looks like the head up display gets it's power from the switch, and uses the same ground as the switch. If you feel confident in trying to diagnose, I can try and offer some guidance. I would guess that it is either the switch, or the display.
