1G Convert CD / Tape input to Auxiliary / Bluetooth input on Stock Radio

[eyebrowski]

I would like to keep stock looking head unit in my car but add Bluetooth.

Has anyone used the cd input to add RCAs? This would allow me to attach a Bluetooth module. I've attached a couple pics of head units I am looking at.

Does anyone have the pin outs for the CD input?

There was at least a factory 1g radio with an auxiliary input (2g I couldn’t tell you), I had one but sold it a few years back and never used it, don’t know how common they are but they do exist.

 

[eyebrowski]

Thanks but I am looking for something a little older (~1990) and would like to have it all wired up behind the dash rather than use a front panel input.

 

[Spleen8urLSX]

Ah ok that makes sense! I like the idea of having it tucked away like that where you don’t see it.

You mean the round connector right? Is yours 13 pins or 6 pins?

 

[eyebrowski]

Correct, the 13-pin connector. I found the pin out info, it appears to be common across all (most?) Mitsu head units.

There are a couple of variations I found when searching. The one you have there, and another. You’re on the right path though

This is the same diagram just showing the header pin out vs the cable pin out (inversed)

I think you answered your question

Keep us posted. One other question might be whether the sound signal gets amplified by the CD player unit or the head unit…

It would be great if someone could figure out how to do it with the CD changer input.


I did this on my stock 1997 Saturn SL2 a few years ago, worked great (requires soldering):

How about an FM modulator?
Tucks away, goes inline, you just have to broadcast to it.
(My hobbies include Ham and Modifying CB radios for lots of "extra" stuff).

If I were going the authentic/vintage route this is how I’d go. Or one of those tape adapter things from when I was in high school… those don’t exactly tuck away though No hacking wires, etc. Not working with THX rated sound booths here…

But, I use a single DIN Bluetooth head unit (no CD) with the Metra plug adapters, so no hacking. The OEM tape deck (not connected) is filling the spot below it instead of a pocket. Conversation piece.

It looks like the 3S guys have figured it out. Super simple. I’ll go RCA and use a Bluetooth module powered off the DIN connector. I may try to figure out the closure contact form the tape/CD unit so nothing needs to be inserted.

How to: AUX input via 13pin CD Changer Connection

Installed an Aux input to the mitsu stock CD Changer/Stereo in the Stealth last night and thought I'd share. I know there are pre-made wire's/kits out there, but in case you want to do it yourself this might help. Sorry if it's a bit crude, it's my first how to :) Applies to: CD Changer/Head...

You'd be taping into the cassette head for that and it would look stock (if we are thinking the same thing).

 

[eyebrowski]

Exactly, this will keep it nice and clean.

 

[ErikTande]

I tried one of these but it didn't work.

Unfortunately, something like that won’t work for us. Not all DIN connectors are wires the same and you also need a contact closure to activate the input on the head unit.
