2013 F-250 sync 2 to 3.4

[davidwhitson]

I installed a new radio (sync 2 to 3.4) and now the seats heat and cool will not work. The buttons are on the radio. My fan and Temp will not work on the radio. The seek and PTT are the steering wheel buttons don't. I have looked a spreadsheet for 2013, I am having a hard time finding one. Can someone help me with this?

I did the same conversion you did using a junkyard head unit. Had to get into forscan and copy the values from the sync 2 system over to the sync 3 system to get them to work. If I remember right, you'll find the values under the APIM module in forscan.

There's a guy out there that pre-programs these sync3 units and you can get the whole kit for like $600.

You can diy it, but it's a pita for sure. Trial and error.
