Keep OEM microphone with aftermarket HU

Has anyone been able to keep the factory microphone in their 2nd generation tacomas?

I found this post by cinemagic on tundra forum - wondering if it is a similar process

[FONT=&quot]For the Microphone:[/FONT]
[FONT=&quot]I did a substantial amount of wiring, trouble shooting, building of power supplies, and legwork…to be beat by the OEM microphone amplifier. In the end I tried the simplest of things; I bypassed the Microphone amplifier and simply connected the factory microphone. This gave me a microphone that fit perfectly into the location and worked great. The OEM mic DOES NOT need the amplifier when used with the Eclipse head unit, and I can assume this is the same for all head units.[/FONT]

[FONT=&quot]I tested with a parrot mic and the Eclipse mic, both held in numerous areas of the vehicle, and in ALL cases the Toyota OEM mic was the clearest.[/FONT]

[FONT=&quot]To bypass the amplifier is easy, here it is:[/FONT]

[FONT=&quot]Behind the factory radio, on the k7 connector, connect the following:[/FONT]
[FONT=&quot]Toyota Brown wire = Tip + of a mono 1/8” headphone connector[/FONT]
[FONT=&quot]Toyota Yellow = Ring – of the headphone connector[/FONT]

[FONT=&quot]At the microphone in the headliner, Remove the mic and do the following:[/FONT]
[FONT=&quot]1. Cut the four wires between the plug and where they enter the wire bundle. [/FONT]
[FONT=&quot]2. Connect two pieces of wire to extend the Brown and Black wires, 3” works fine.[/FONT]
[FONT=&quot]3. Mask off or heatshrink the extra wires.[/FONT]
[FONT=&quot]4. Open the mic casing and expose where the mic connects to the amplifier.[/FONT]
[FONT=&quot]5. Solder the new wires to the circuit board where the mic connects.[/FONT]
[FONT=&quot]6. Connect Brown to the mic +, and Black to the mic -.[/FONT]
[FONT=&quot]7. Re-assemble the mic and install in the vehicle.[/FONT]
[FONT=&quot]8. Plug the mic into your head unit.[/FONT]
[FONT=&quot]9. Enjoy the factory microphone!!![/FONT]

[FONT=&quot]I hope this helps others; it took a long time to gather all of the information. I will post other documents to support the wiring diagrams for the vehicle.[/FONT]

[FONT=&quot]Good luck with you installation!!![/FONT]

 

Very cool, I've got to take my deck out and put in the steering wheel control connections. I'll check into this on mine.

Thanks for the tip

 

I came across a post last year where someone was able to make it work with a pioneer HU. I didn't try it, so I can't say if it does truly work. Try searching and you may find it.
