Hello all! I apologize in advance if this is a duplicate post, but I have searched the forum and cannot locate any specific information on this topic. Does anyone know what wiring harness/interface adapters I will need to swap out the factory Sync with the 4.2" screen to an aftermarket double-din stereo in the 2016 ST1? I have searched these forums, Crutchfield's website, Metra's website, Scosche's website, iDatalink's website (for Maestro), but none of them have anything listed for wiring for the ST1 with Sync 4.2". I have tried a local chain audio installation place and they said they can't do it because they can't find the parts. I checked with a nationwide electronics store that does car audio installations and have been told by one installer that they can do it and that I just need a wiring the Metra wiring harness and no interface box, and that they can splice into the wires to make the backup camera functional, but then a different installer told me that no, I have to have the Maestro wiring harness and interface box.
Can anyone provide any clarity on this?
