- Technical Discussion and Customizing your H2 (http://www.elcovaforums.com/forums/forumdisplay.php?f=5)

- - Auto Volume (http://www.elcovaforums.com/forums/showthread.php?t=512)

I took my H2 in to the dealer for a bunch of other minor things, and was told that the auto volume only adjust the bass in the vehicle when the interior noise level goes up or down. It is not speed dependent. There was supposively a tech report on this. Does anyone have any info on this, or is the dealer full of it?

Thanks,
Ric-H2

I don't have technical info, but can tell you it sounds like the highs and mids get louder in addition to the lows. I don't know if it is speed sensitive however, it seems to me it only gets louder when I get on the highway.

Anthony,

Are you implying that your auto volume works? If so you are the first person to post on here that it actually works.

Ric,

I do believe that it is supposed to be the full spectrum not just the base. I believe your dealer is blowing smoke

What in the f*ck is supposively?
I think we've all heard the poor word, supposedly, butchered into supposebly, and Ebonically as stupposibly, but supposively is really scraping the bottom of the ****ty spelling barrel. Damn.

I took mine into the dealer for the same thing and was told it is working fine. I have yet to hear any difference in volume whatsoever. It was very evident on the radio in my Avalanche.

<H5>Cause</A></H5>

The wires to the noise cancellation microphone may be installed in the

<H5>Correction</A></H5>

Install the noise cancellation microphone wires into the correct cavities at
the audio amplifier module using the following procedure:</P>

<LI type=1>Remove the center console in order to gain access to the audio
amplifier module. Refer to the Console Replacement procedure in SI (Document
ID #834656).
<LI type=1>Disconnect connector 1 (Light Gray, 24 way) from the audio
amplifier.
<LI type=1>Locate the two wires (circuit 1354, Light Green/Black and circuit
1488, Dark Green) in the connector for the noise cancellation microphone. They
are in cavities B1 and B2 of the connector.
<LI type=1>Remove the two wires from the connector and reinstall them into the
opposite cavity from where they were originally. The Light Green/Black
(circuit 1354) wire should now be installed in cavity B1. The Dark Green
(circuit 1488) wire should now be installed in cavity B2.
<LI type=1>Reconnect connector 1 to the audio amplifier module.
<LI type=1>Install the center console. Refer to the Console Replacement
procedure in SI (Document ID #834656).
<LI type=1>Verify the operation of the noise cancellation microphone and the
Automatic Control Feature of the Entertainment System.
<LI type=1>If the Automatic Volume Control is still inoperative, refer to the
Diagnostic Starting Point-Entertainment (Document ID #684715) for further
diagnosis. </LI>

Mine is definitely working. It seems the faster I drive (to a point) the louder it gets. Makes sense. More road noise at higher speeds then tooling around at 20mph.

Cinci,

Yeah ours works. Was in it yesterday and it did get louder- not just the bass.
