^^ I'm surprised that your installer used a separate speaker for navigation voice commands since you have a mute wire/function with this H/U. I would prefer having the voice commands broadcast through your CES speakers.
Your H/U with it's mute function supports this, and doing it that way keeps the volume at the same level.

spike, how does one go about doing that?
even if you can auto mute, how do you make the signal from the navi module, go to the amplfiied aftermarket speakres? you cant hook them up inline, or else the power from the amplifier, travels right up the wires and fries the navi module's output. but if you know someitng i dont, please share hehe, i am pretty sure a some kind of relay needs to be biult do accomodate this, but i still wouldnt risk it, one loose wire off the relay can mean puff goes your stock nav...

and i do believe he means the volume out the STOCK navi is too low? not the voice out of the jensen unit, whcih prolly isnt a nav unit?
to the OP, when you wire a speaker inline from the nav voice output of hte stock nav, the volume is indeed low, lower on the nwer Zs (post 05) than previous, but it is low, ther eis very little you can do about it...
espeically if you have bose, previously, the voice was run through the bose amp first and then amplkfieid through the stock separkes, no its direct line level so its going to be low...
solution, well, you can add a tiny POS radio shack amplifier inline with the nav speaker, but its a bit annoying and takes a lot of effort.
the other way is to reroute some wires from a stock bose location, connect hte signaloutput from the nav to one of thos wires, and still hae the signal wash through the bose amp, but this is even more comlex and way more work
what i usually do, on 350z aftermarket systems, is since i only change and amp the front stage, i retain one of the rear stock bose speakres, for nav voice, and hook up the nav voice output to the rear speaker wires in the harness, this way, its super loud and clear behind your head when it talks. but again, I do this beucase i dont do rear speakres in the Z when doing a system.
my whole point in the end is, what they did, is the normal way to do it, any way to make it louder is a significant amount of work...

It's so easily done that I may be missing your point.

More explanation on broadcasting navigation voice-commands…
In my previous post (directly above), I said that broadcasting navigation voice commands was simple, but never described doing this. That makes me sound a little bit like a jerk.
So… here is more info…
If you have an “all-in-one” device that has navigation, LCD screen, and H/U in a double-din configuration, you can expect this to work without much trouble.
If the H/U supports muting, you simply connect your navigation sound-out to the AUX input on your H/U. The navigation device sends the start-mute signal, and then sends the voice command, followed by the end-mute signal. The H/U (that supports muting) automatically switches the sound output to the AUX, broadcasts the navigation voice commands, and then switches back to the current H/U’s output (radio, CD, etc.). It’s totally transparent. You can adjust the volume using the navigation device’s feature for this.
If the H/U does not support muting (no built-in muting feature), you can still broadcast your navigation voice commands through the car’s CES by adding a PAC device. The PAC device goes between the H/U and the external amplifier, and the sound output from the navigation device and your H/U sound outputs are wired to the PAC device. The PAC device respects the muting signal so you can broadcast navigation voice commands and automatically return to the current H/U’s output (radio, CD, etc.) . This way, you can even select specific speakers (i.e., the fronts, rears, or any multiple or single speaker) to broadcast your navigation device’s voice-guidance and simultaneously play the current entertainment from your H/U.
