IJUST GOT 2 JL SUBS AND COMPONENT SPEAKERS FOR DOORS,AMPS AND PIONERE AVICD2 HU...I HAVE THE STOCK NAV SYSTEM BUT THE INSTALLER IS TELLIG ME IF CHANGE THE STOCK HU THE NAVY IS TRASH AND I GOTTA GET RID OF IT?IS THIS TRUE?THE NEW HU HAS NAV SYSTEM ALSO BUT I WAS PLANING ON USING THE STOCK NAV SYSTEMCAUSE I PAID BIG BUCKS FOR THAT OPTION WHEN I BOUGHT CAR FROM DEALER ANY ADVICE? BY THE WAY ITS A 2003 TOURING.....

 

I believe the nav is designed to go with the HU. If your new system has a nav no worries, ay. Your best bet is to either save it to swap back in if you sell the car.

 

^^ You can keep the stock navigation system when upgrading your H/U. In fact you should since it adds value to the car.

so thats 1 for yes and 1 for no, anyone else know anything that can help me?

 

you can keep the nav and it will work fine, the only problem is that you loose the voice guidance.

 

^^ A search on this sub-forum show a couple of different implementations you can use to maintain the Z's voice guidance from the stock OEM navigation when swapping out the OEM H/U.

I'm not sure if your installer meant that the stock navigation is "trash" in the sense that it is no longer able to be used when you install an aftermarket headunit or whether he or she meant that it is "trash" in the sense that it cannot compare feature wise to the navigation systems that are out on the market today (both aftermarket and OEM since your car is a 2003 like mine). Either the way the former is incorrect and the latter can be correct depending on your needs.

The stock navigation will work fine with an aftermarket headunit, like one of the posters above mentioned the only thing that you will lose is the voice guidance feature when switching to the new headunit. However, once again like one of the posters above me has also mentioned this feature can be regained and there are several threads on this board which detail step by step how to do so.

I have a 2003 and I switched to an aftermarket headunit. I installed an Alpine SBS-0715 (discontinued) amplified speaker discreetly under my dash and wired it up to my OEM navigation system in order to regain the voice guidance feature. MY OEM navigation system works just like it did when I bought my car in 2002 with the exception that I lost the radio mute feature when the voice guidance system is activated (this is not due to anything other than the fact that my Mcintosh radio does not have a mute feature, otherwise I would still have the radio mute intact.) Any who, if you do some more searching on this board you will see that all the answers to your questions have been answered since way back in late 2002 when these cars first came out.

 

^^ Nice post with the right answers.

Just so that it's perfectly clear (and realizing that you know this but others may not), you can support muting an aftermarket H/U that lacks this feature by adding a PAC device to your CES.

Spike,

Thanks for that tidbit of information. To be perfectly honest I was not aware of that and I am definitely not stubborn enough to not admit something at the risk of learning something . If you don't mind please explain how this can be done either by posting here or through PM.

Thanks,
Kwame

 

I have these components:

• Clarion DXZ745MP H/U with a Sirius satellite radio receiver
• Eclipse 4 Channel Amp Model EA3422 (driving front components and rear coaxials)
• Focal 165 V Slim component speakers in the doors (tweeters mounted in the A-Pillars)
• Infinity coaxial speakers in the rear speaker space
• Power Acoustik PT-700MHR LCD 7” Monitor in the upper/forward cubby space
• Garmin GVN52 Navigation Box (mounted in the rear cubby space behind the driver’s seat)
• PAC Audio Source Switcher (mutes radio when sending navigation voice commands to the front speakers)

I wanted to have the voice guidance commands from the Garmin GVN52 to broadcast through my front component speakers and mute the radio or CD (whichever is playing). I have the rear speakers tuned way down (via the H/U’s fader function). When the Garmin issues voice guidance, it comes through the car’s front component speakers loud and clear, but the radio still plays through the rears (but just a little).

Although the Garmin GVN52 Navigation has a mute wire, the Clarion DXZ745MP H/U does not support a mute function (i.e., toggling from an AUX connection to the current audio-out of the H/U). To handle this, I installed a PAC Audio Source Switcher. I connected the Garmin’s audio-out and the Clarion’s audio-out for the front speakers to the PAC Audio Source Switcher, and from the PAC to the external amplifier.

EDIT: I should mention that Paul350Z (a longtime Forum member) is actually the one who gave me the idea on how to this. Paul mentioned that restaurants use this configuration inside their public address systems so that the music playing is interrupted when a seating is announced (i.e., “Spike, your table is ready”).

 

Gotcha ya. You are correct in your initial assumption, I am aware of how to setup a system such as yours. I think my confusion lies in how I can integrate the radio mute feature within my own setup. I was aware of the PAC audio source switcher maybe its just too late and i should be sleeping but I can't think of how it will work with my setup since I have a whole seperate speaker thats sole purpose is for the OEM voice guidance feature.

I'm not using the same speakers. So different sources, different speakers. Am I missing something?

 

^^ I understand.

My Audio Source Switcher is an older model (about 4 years old), and I don’t think it has the capability to handle your setup (i.e., a separate speaker for the navigation device). I do believe the newer PAC Audio Source Switcher and its expanded features would work for you. I think (not 100% sure though) the newer device allows multiple inputs along with multiple outputs. If the PAC device won’t work, there is certainly another company that has this feature. Or, I suppose you could disregard the separate speaker and just route the output through your CES’s sound.

There is a caveat that I didn’t mention in my previous posting. You must have exactly the right resistance on your devices to make this work. That took awhile and some testing with different resistors to get it right (too much resistance and you don’t get any sound, too little resistance and you get “popping”). I had an awful time with this and finally took the car to a professional installer for this needed adjustment.

In the end I would say it is very nifty to have your CES mute the current audio (e.g., radio, CD player, iPod, etc.) while voice navigation issues driving commands, and then automatically return to the entertainment channel.
