Ok, finally figured out the problem here. The dang e-brake switch was broken! Replaced and... the greyed-out buttons are gone. thanks for the help!

Ok, you're correct about the status messages. It indeed states it is not receiving a parking brake on signal. I have done the "hack" repositioning the mute wire and then grounding it with the green wire... no worky still I am scratching my head here. Thanks so far.

Yeah It did work in the car. The original AVIC-D3 installed in the car - had a malfunctioning DVD player, mechanism broken, navi system would not work. I know before the DVD system broke, all those buttons were working OK I bought a working used D3 unit. I unplugged all from the old unit, installed the "new" unit (basically took 15 mins). Everything is working expect the navi buttons are all greyed out, cant input an address, etc..

I am trying to figure out why my navi buttons are all greyed out. I'm stopped, parking brake pulled....
