sync headliner mic with aftermarket radio

Post by chefboytony » Mon Sep 26, 2016 1:35 pm

Hi

I have a 2012 F-150 XLT Super Crew with sync, and I am in the process of replacing the factory radio with a Kenwood DDX793. I purchased the Maestro RR and the F01 harness

I would like to eliminate sync all together, so was wondering if anyone knows which wires/colors on the sync module harness are for the factory headliner microphone? I'm looking to splice/re-terminate it to a 3.5mm TS plug so I can route it to the kenwood unit.

Thanks!

We don't have the Microphone wiring information database. From our testing, we didn't have good results on integrating the the factory mics to the Aftermarket Head units.

ah ok I see thanks.
Do you have the pin out for the 54pin sync wire harness connector? I'm also looking to tap the sync line in 3.5mm TRS socket

Thank you

We don't have it offhand, but we really recommend against splicing into that.

So, I have a 2012 F150 XLT with Sync Basic. I have been reading the many threads on the headliner mic and this one has been the most enlightening by far. It really sounds as if the factory microphone is a balanced condenser mic and that the 3 leads out of the microphone would be a balanced connection. My theory here is to properly operate the mic on an aftermarket head unit, you would need a couple of pieces of hardware....

1. A 3 pin to XLR adapter such as this one. https://www.bhphotovideo.com/c/product/ ... oenix.html

2. A phantom power supply like this. https://www.bhphotovideo.com/c/product/ ... ingle.html

3. An XLR to 3.5mm TRS adapter. https://www.bhphotovideo.com/c/product/ ... emale.html


This should both unbalance the mic connection and insert the (from what I can tell) 12v to the microphone to make it operate properly. I think the power supply is the issue previously since I would doubt that the unbalanced TRS output from the head unit puts a solid 12v source to power the microphone. You would just need to wire the 12v input on the power supply to an acc switched lead in the harness somehow.

Perhaps ADS could come up with a more elegant "roadworthy" solution to this as an add-on?


Now I just need to figure out how to mount this....

sorry for not updating this post. I actually found the information in this thread accurate to my 2012 F-150 even though the poster as a super duty

I followed his steps and was able to hack the factory headliner mic to my kenwood ddx793. The color of the wires turned out to be the same

So, did it actually work? I followed those steps as well but I think the sync mic is way too sensitive for the Kenwood head unit. With the microphone gain set to -10 and echo cancellation maxed out, I'm still hearing a bad echo on the other end.

For clarity, I did a test with my wife in another room. Called her from the head unit using the sync mic. She heard me perfectly clear. When she would speak, she'd hear an echo of herself talking. I've determined that the mic is picking up the audio coming from the speakers.

ykno its been working just fine for me for a few years now, not sure why. Don't know if this matters, but in my 2012 F150 XLT I upgraded the stock speakers to Rockford Fosgate Punches.

Interesting. I wonder if it has to do with the layout of the cab. I forgot to mention that I did it in a 2011 Mustang. I ended up solving my issue by putting an adjustable attenuator in line between the mic and HU. I was able to lower the feed from the mic enough to get rid of the echo/background noise and keep my voice clear.
