Ok, I decided on upgrading my system. I'm going with the Alpine CDA-7995 HU, and Alpine in-dash DVD player, and all Alpine speakers and amps. I'm also getting the double din dash plate. Here's my question: Since I also want to get a TV tuner for converting my Nav, should I still opt for the AVElectronic unit or should I get any tuner? Will the AVElectronic be any easier to install (being that only 1 wire requires splicing), or will the fact that I'm changing my HU make any tuner installation easier? Please help, I'm a little confused?

Also, do you think one Alpine 12" Type R sub will do a good job?

Thanks,
Ballzzz

 

don't you lose ur nav voice guidence when u install aftermarket headunits?

I don't know, do you?

I would think you lose it. Not unless you keep the factory head unit and use the high to low converter.

wow, that really sucks. so i guess i should just scratch the whole upgrade? i mean, could the stock hu really be that good for a hi-fi system? what do you guys think?

Frankie,

i think there are a few members here that have that setup and seem to love it. Search for it and maybe, u never know, that member might be close to you.

I have installed the Double-Din and CD Player....

In additional, I have installed the AVElectronics Nav-Tuner... I still need to finish the Tuner install on Wednesday, will post more pics then

Here is my double-din and HU



Right now the Nav voice doesn't work, but there is a way to get that to work... some one at my350z.com got that to work... have to dig it up again...

What you will need is to get a self-powered center-speaker

is the NAV tuner sound quality good? I am very interested in one, but I think the sounds are transmitted through FM modulation, please correct me if I am wrong.

Linking the factory nav system to a new head unit...
For those of you trying to install a new head unit in your Z, but keep the existing factory navigation system, and keep the voice, the info below will work ! THis is what I did, and it works great, just like the factory navigation system does. Keep in mind that you will have to have a Mute capable head unit, and you will have to wire a seperate speaker for the nav voice. A small price to pay for the much better sound you will get out of an aftermarket head unit.

Anyways, here is what I did:

The output of the NAV system is about 7.5-9 volts. This is not enough voltage to trip a standard 12 volt (30A) relay. So, what I did was this. You have to setup a 2 stage system, composed of a transistor and 12v relay, to switch the mute circuit on a new head unit.

Parts I used:
1. Potter and Brumfield 12V Relay (Bosch will work too)
2. TIP31 high power NPN Transistor (Radio shack sells it)
3. Various length wires and crimp-type connectors
4. 1 kohm resistor (1/4 watt)

NAVI-SYSTEM WIRE MAP:
Mute wire from NAVI control to head unit - R/B
NAVI earth ground - B/P
NAVI Voice input + L/B
NAVI Voice input - W/B

Transistor circuit:
All transistors consist of a Base (B), Collector (C), and an Emitter (E). The pacakge will tell you, if you buy it from ratshack, or look online for a datasheet for your transistor. THis circuit will work for an NPN only. A pnp transistor will be wired differnetly, so make sure you get the proper parts !

1. Wire Mute (R/B) from NAVI control to the transistor Base (B) through a 1kohm resistor (Limits the current so you don't fry the TIP31).
2. Wire the Emitter (E) to vehicle ground
3. Wire the collector (C) to postion 85 on 12V relay

Relay CIrcuit:
1. From 3 above, wire the output of the collector to position 85 of a 12v relay.
2. Wire postion 86 to 12v switched by the ignition (only on when key is on)
3. Wire postion 30 of the 12v relay to vehicle ground
4. Wire positon 87 of the 12v relay to mute input on the new head unit.
5. Position 87a is not connected

Here's what happens:
When the voice control turns on for the navi system, it send the R/B wire high (7.5 volts). This voltage triggers the transistor to open up, and essentially provide ground to the relay. Once the relay is grounded, the relay is energized, and switches the constant ground (suppleid by terminal 30) to position 87, and supplies a ground signal output from the 12v relay. This ground signal MUTES your new head unit. THat's all...simple circuit, great results !

Don't forget that you will have to add a seperate speaker for navi voice under your seat, and run the 2 voice output wires from the navi control to this speaker. If you mount it under the driver's seat, you may have to turn the volume up slightly to hear it...

Good luck, and I hope this helps those who are adding aftermarket headunits to a Z with factory navigation...

great find, i had actually posted this idea on this board a few weeks ago but got only one reply. I figured there was a way to get this to work. Ill be doing this eventually...great!

That was the post that I was referring too....

The NAV-tuner sound will be going through my AUX-IN to my headunit....

 

sorry..i got a newbie question...
will the installation AVElectronic TV-tuner let me beable to watch DVD/VCD with my stock Navigation system? and since they got AV plugs, can i hook my gamecube to it?

 

Yup...u can hook xbox, gamecube, etc. But you can't use your dvd nav to play normal dvd.

The AV box will let you run a video source to your nav screen while your nav is running as well. You can also watch regular tv with the tuner.
