How do I keep the nav voice with an aftermarket 4ch amp?
With all the recent debate on what is the best way to hook up an aftermerket amplifier, nobody has mentioned the fact that you may lose the navigation voice. I am planning out a whole polk MOMO system and it just occurred to me that I have no idea how to retain the factory voice guidance if I use a 4 channel amp. If the signal is fed into the LF channel before the BOSE amp then I could still wire in an amp using the LF & RF pre BOSE amp signal but the whole left side will mute not just the LF. Any thoughts from the pro's or folks with a wiring diagram? If the signal comes from the nav unit then how do I tie it in with an aftermarket amp so that the speaker still mutes the music? I would love to hear from eXcentric, rotarygod or bob the eskimo on this one.

From what I've read here it's fed to/from the head unit... There is left channel leads back to the NAV for muting the music/etc from that side when the voice is fed on the line.

Bump...
I really need help on this one folks. I sure would hate to put in an amp and lose the Nav voice. I'm sure I am not the only one with a nav system who will be adding an amp. I'm sure somebody out there has added an amp to a nav equipped car.

I chose not to have the NAV system, just to simplify things and what are you going to do 20 years from now when that thing goes out and no one makes that screen? I keep my vehicles at least 10 years, and the body design and interior design on this car is awesome, just wish more power and better MPG

You can add a dedicated NAV SYSTEM SPEAKER!!!, yes it can be done,
you can even add a self powered one w/volume control, the key is to make a really trick volume control that is visually appealing
I don't have a NAV system because I don't need one. It would be awesome for travelling though!
I am a former Automotive Engineer and Electronics Engineer, I say FORMER because although I liked the work it paid crap, I now make twice as much. And much less stress...

I suppose I could've started a new thread, but this was already here so...
But yeah, I noticed the same thing. After I got my amp and speakers installed the music won't mute anymore so the nav voice is all that comes through. If the music is up at all you really can't hear it, only the ding that preceeds it. Anyone else have this trouble?

Interesting...
Why would changing an amp and a speaker make the Nav not come through anymore?

what's a CleanSweep?

What exactly does CleanSweep® do?
1) About the size of a paperback book, CleanSweep® accepts virtually any analog audio signal, from low-voltage line-level to high-power, amplified speaker-level, via its four differential-balanced inputs. With totally automatic level compensation, CleanSweep® then converts the two or four connected analog signals to digital audio with 24 bit effective resolution.
2) CleanSweep® applies the power of its state-of-the-art, 32-bit SHARC® DSP processor to automatically equalize each of the four channels with 30 bands of equalization (that’s 120 bands total), effectively correcting the response of almost any factory-equalized, full-range signal. These digital-domain corrections will range from subtle to dramatic, depending on the degree of equalization engineered into the factory audio system. To accomplish this complex feat, you simply load the supplied CleanSweep® calibration CD into the factory-installed CD player, set its volume control between 1/2 and 3/4 volume, play the designated calibration track and then press the “Calibrate” button on the top of the CleanSweep® processor. Approximately 20 seconds later, the CleanSweep® is finished analyzing and equalizing the factory-installed source’s response and stores the corrections in non-volatile flash memory.
3) CleanSweep® then converts the digitally corrected signals back to analog audio and sends them out to your aftermarket amplifiers through two pairs of low-distortion, 8 volt (RMS) line-level outputs.
4) CleanSweep® includes an intuitive rotary user interface (a **** with stops at both ends) to control the master system volume at the outputs of the processor unit for both the OEM (factory) and auxiliary sources. The master volume eliminates the effects of any equalization that is dependent on the OEM volume control position and allows a high signal-to-noise ratio to be maintained in the system. When pressed, the master volume **** also selects between the OEM and Auxiliary source. A dash-mountable status LED changes color to indicate OEM or AUX input modes. These small controls can be easily mounted within reach of the driver.
5) CleanSweep® can be deployed in signal-sensing mode, powering up and providing a 12-volt turn-on signal for aftermarket equipment whenever signal is detected. It can also be activated by a conventional 12-volt trigger, if the OEM system provides one.
