Question about Metra Car Audio & Video

1 Answer

I have a 2006 lincoln Navigator with the THX sound system. I need a colored wiring diagram so I can replace the head unit and hopefully retain the factory door speakers and amp. I already have my JL Audio 12s and amp ran to the back. So I am not gonna use the factory sub or that amp. Any help would be great. I was told to use a metra harness and I got nothing. Just want to splice into factory harness from my new head unit.

You can buy an aftermarket radio harness adapter for your Navigator from ebay quite cheaply. I would not recommend butchering the factory wiring to install a replacement head unit. I found this one (will work as long as your Lincoln wasn't fitted with SATNAV) -

SOURCE: cd player plays, but no sound comes out of speakers.

Look at the enwood. I bet you have the remote wire hooked to the blue wire insted of the blue/white wire. The blue wire goes dad when you play a cd as it is for a power antenna. The blue/white wire is your amp turn on.

Now, if you do not have a blue/whie and only blue, then obviously that circuit in the radio is bad in whch case your only other option s are either connecting it to an accesory fuse or using a toggle switch connected to power.

SOURCE: need color code diagram for factory 8 speaker

On my 99 4 door the factory amp is powered by a hot pink wire in the truck harness. I hooked the cont. power for a motorized ant. to it and all 4 speakers work. I'm going to check today to see if they work correctly because I found this out late last night and only had it on for a few minutes. I've read that there is a harness for this that apparently you have to specifically ask for at a car audio shop. hope this helps.

My rear DVD player in my 2010 F-Expd was working but then we changed the disc and it made a weird clicking sound like it was trying to read and gave a load disk error. It does this w/every disc.ideas?

Hello Ammie Gordon,

If you have this same response from a couple of DIFFERENT DVDs (combined with your "noise" symptom) then it is safe to assume you are having a head/drive issues ...

These units are quite robust, cleanable and serviceable... but my best ADVICE is they are also fairly INEXPENSIVE (not cheap) and available (on eBay as well (in colors)... ADDITIONALLY... identical unit were equipped in the 2010 Lincoln Navigator.

I would get a COMPLETE REPLACEMENT and have the SALAMI removed by your ORIGINAL by your favorite uncle in your leisure time...

Hurry... BLUETOOTH "PLAYLISTS" and streaming media are right behind this technology... and ...
these will be as hard to find as 8 TRACK tape players
(I'm just saying).

Hope this helps.

Aftermarket head unit installed but no sound comes out

You need to make sure that you are using the correct adapter harness as the speaker has to go from stereo to the factory amplifier and it sounds as if it isn't completely wired yet
