OEM Radio configuration change

Customer Question

I have a 2004 expedition...

I have a 2004 expedition with the audiophile sound system that I added from another expedition. I am unable to make the subwoofer work properly unless it is in the speaker walk around test. During this test, when it gets to SUBWOOFER II, the sub works fine. I believe I need to change the configuration of the radio but have no procedure to do so.

Customer reply replied 13 years ago

The DSP button only allows me to adjust the ambiance level. So - I guess the answer to your question is no.

To enter the speaker walk-around test, simultaneously press the audio unit preset buttons 3 and 6.
The speaker walk-around test stops at each speaker and applies sound to each speaker for about one to two seconds. Each speaker is tested and displayed on the audio unit in the following sequence: RF, LF, LR, RR.
The speaker walk-around test automatically continues and tests for the operation of the AM/FM antenna. If the antenna is inoperative, NOT FOUND will be displayed. If the vehicle is not equipped with CD/DJ, or if the CD/DJ is not responding, NO DJ will be displayed.

Speaker Walk-Around Test — Navigator with Navigation System (late build only)

NOTE: To enter the speaker walk-around test or audio unit self-diagnostic mode, the audio unit must be turned on and in radio tuner mode (AM/FM).

To enter the speaker walk-around test, simultaneously press and hold for five seconds the audio unit preset buttons MAP and DEST.
The speaker walk-around test stops at each speaker and applies sound to each speaker for about one to two seconds. Each speaker is tested and displayed on the audio unit in the following sequence: RF, LF, LR, RR, Subwoofer.

Speaker Walk-Around Test — All Audio Units Except VNR

NOTE: To enter the speaker walk-around test or audio unit self-diagnostic mode, the audio unit must be turned on and in radio tuner mode (AM/FM).

To enter the speaker walk-around test, simultaneously press the audio unit preset buttons 3 and 6.
The speaker walk-around test stops at each speaker and applies sound to each speaker for about one to two seconds. Each speaker is tested and displayed on the audio unit in the following sequence: RF, LF, LR, RR.

Hey bud did you not get any dtc's ? And that page I sent you said to press button 4 for the configuration set up and then press tune to scroll through them if I had a system like that here I would be playing with it to try to help you out with on-hand but all I have I already sent you. And I guess button 2 will run dtc checks for you. So please let me know and I will do my best to help you fix this problem other than that I think your going to have to play with it and figure it out try the dtc step and see about any codes ok. And know even after you pay I'm still right here if you need any more info ok thank you and good luck. Let me know what you find out
