Is this after the navigation retrofit? It sounds like your radio module is not connected. Try verifying that you are getting power at your radio module.

Also (this may seem basic, but I want to cover the diagnostics basics), you turn on the radio by pushing the left knob on the 16:9 display.

Do you have DSP? If so, do you get the "DSP" menu option on the main menu of the nav screen? If not, verify that you have power at the DSP amp.

Yes, I am aware of the operation of the navigation screen lol. I know its a simple, yet possible question and it has to be covered.

The BM 53 Radio IS getting power to it (checked it already)

I have checked all fuses, I checked for broken/bent pins, checked the wires, ect.

I dont have DSP

Whats other fact is that when I go into the settings menu and change the volume of the navigation part, there is no tone???
