With the radio removed, you are looking for the harness that has Blue/White and White/Black wires in it. It’s the same harness that has the speed sense wire in it.(White/Green)



BooYeah!


Already have your radio installed and don’t feel like taking the radio out? Drop the glovebox, look up and the white plug on the left will have the wires in there as well. Careful when dropping the glovebox, I’m pretty sure the bright yellow connector and wire are airbag wires.




Blue/White is Nav. Voice (+)
White/Black is Nav. Voice (-)

Strip both these wires and splice speaker wire to them. I think these wires are pre-amped and will have a low output but I haven’t gotten to that point to test them. The car has to go to the dealership to fix a U1000 code. As soon as it’s back, I’ll update the thread.

If it is a preamp signal, and since I already have a sub in the car, I will be using the stock amp(should be bypassed when you installed the aftermarket radio) to boost the signal to the speaker I will be installing in the stock sub location on the back deck. If it’s not, I should be able to run it straight to the speaker.

 

where were you 2 months ago.. damnit...

 

lol, car is finally going to the stealership Friday, should have this finished up middle to the end of next week I'm hoping

 

When doing this, will it lower the volume of the music being played so that you can easily hear the nav voice?

 

It will not, unless the radio you have installed or would install has a mute wire. You would then need to pulse that wire while the navigation is speaking. I have not looked into that too deeply, but I'm pretty sure the stock radio uses the nav audio inputs as the trigger to mute the radio

 

Nice write up!

 

got a question (asking opinion lol)
i have an 05, and it doesnt have bluetooth. for now im keeping the stock HU, so i was thinking- if i butchered my bluetooth speakerphone, do you think it might be possible to feed audio into the headunit through there for phone calls?

 

Been there, done that. It worked decent if the volume was kept somewhat low, but if the volume was too high, there would be feedback/echo. And by high volume I mean average listening level at say highway speeds. You would need the aux in adapter that uses the sat radio button, and depending on the plug that's on your BT, convert it to RCA inputs. Alot I have seen use simple headphone plugs

 

hmm... but as long as i know it works... my other option is my phone has an audio out, so i could wire that in also. when my CD player was down, i used the aux in. however, now i have to have a bluetooth, lower the volume ect..
hm well now i have a new project thanks man!
