What im saying is that nav screen is blank/black buttons do nothing for nav or audio, except that its still illuminated. if everything worked except sound then that would make sense...

FYI the illumination system runs independently so the buttons would illuminate regardless of what the nav/radio system is doing.

I have a few thoughts.

I would check your fuses first. I think there are 6 total fuses for the nav/radio system. You might have popped one when you disconnected the amp.

If you didn’t hook up a new amp to the source lines there might be safety feature that disables the system if it doesn’t detect load on the source lines.

which fuses? I checked over all of them and they look fine, I did use a fuse checker, under the hood I only found 1 for hvac under the dash there weren't any specifically marked as hvac...

The system is integrated into the bose amp more so then just audio. I remember tin the 350z's that if you didn't ground the bose amp after swapping out a head unit the locks and windows wouldn't work right so yeah I can see it's a possibility that the system might not work right.

Should be fuses 3, 4, 5, 8, and 19 in the passenger compartment fuse block (left side drivers side foot well) and fuse 34 in the battery compartment fuse block. The nav/stereo shares fuses 3 and 19 with the HVAC.

Well it’s not the fuses then.

BTW if are looking for help please include as much info as possible.
Your issue was vague and you didn't say what you were trying to achieve.

If I had known you were trying to delete your factory NAV and that you had wired in the Non-NAV HVAC controls wrong, I would have approached your issue differently.
