Questions for you A/V guys & gals.

2016 F250 XLT. Had the sync with the standard CD player and on the steering wheel I had Volume Up/Down, Seek Up/Down, Voice, Ok and the Telephone Button. I installed a Pioneer DMH-W2770NEX stereo with the PAC RP4-FD11 Wiring Interface. Install went smoothly, took about 3-4 hours for everything but I was taking my time. The PAC adapter actually looked up pretty easy and buttons programmed well. So Volume Up/Down, Seek Up/Down, and media all work well. The Voice button is working as the system mute which I am okay with. It says in the directions that some of the buttons would need to be hardwired. I was wondering if any of you have been successful at getting all the buttons to work for there intended purpose without hardwiring, because I am not messing with that, and it would be nice to have the OK and Phone buttons work if possible.

Also randomly and not every time the radio switches back to the main menu by its self. Radio says running and goes right back to normal function. I am wondering if it has to do something with the sync system and the 911 assist that would always pause the radio. Can I turn sync completely off through FORScan or will that kill my steering wheel buttons? Sorry for all the questions, thank you for the help. Loving the new stereo no matter what.

 

i have never had any luck getting steering wheel buttons working properly with aftermarket stereo units.

 

I hear ya. I am super surprised I have as many as I do working. Just really wish I could pick up the phone with the button.

 

I would suspect Sync is causing your issues, I suggest using the forscan to shut it off and try again, if it doesn't make a difference you can always turn it back on with forscan. In my 2012 with a Pioneer system and using a iDatalink interface I had no issues, but I also deleted the Sync app from my phone.

 

so all your buttons work?

 

cant see how sync would have anything to do with it since it is part of the radio that was removed from the truck.

 

Yes they do.

 

If I recall correctly Sync is a separate module from the radio, because when I swapped out my radio, and didn't delete the Sync app, Sync was still connecting to my phone.

 

It was not that way with my 2014 f250 gas truck.
once the sadio was removed sync was gone.

 

Well I went through FORScan, didn’t see anything to “turn off” sync. And didn’t want to just start experimenting. My phone was still connecting after the radio was out until I “forgot” the sync in my Bluetooth settings, so something is still getting power somewhere. I did get the radio to stop turning off briefly by turning off the “call 911” setting in FORScan.

Still will need to get the buttons figured out. Might try calling the company that sells the adapter and see if they have any pointers.

 

Take that back. Truck still “pauses” the radio after 1/2 a mile or so. Have to tap the radio button again to get it to play again.

 

Could also be the interface, I used the iDatalink Maestro on mine.

 

Where did you connect the output of the rp4-fd11? I got the radio working but no steering wheel controls.

 

Here’s the owners manual for the RP4. Ensure all your settings and connections on the interface are set correctly to the head unit you’re using. https://pdf.crutchfieldonline.com/Im...541RP4FD11.PDF
