Intro
This write-up is written based on a 2015 Pro-4X with a Rockford Fosgate system that has the navigation upgrade, and a built-in backup camera. I'm sure this is likely applicable to all 2.5 dashboards, and most of it is applicable to non-nav and non-RF systems, I am open to updating upon confirmations. The goal was to make it so I didn't have to cut any of the factory wires, and to retain as many of the factory connections as possible.Parts Needed
Head Unit: Take your pickWiring Harness (RF, Nav): Metra 70-7553
Wiring Harness (Non-RF): Metra 70-7552
GPS Antenna Adapter (Nav): Fakra C Male to SMA Male
AM/FM Antenna Adapter: Metra 40-NI12
USB Cable: USB A Male to USB Mini B Female
Steering Wheel Controls: Axxess ASWC-1
Aux In + Rear Camera (Nav): Axxess AX-NIS24SWC-6V
Notes for some of the parts
I bought both the Metra 70-7552 and 70-7553 as most of the online databases list the 2 as the correct one, it is indeed the wrong one for the RF system with the amp. However, both of them are missing the pins for the steering wheel control, so I did take 3 of the pins out of that adapter to put into the other one so I didn't have to cut vehicle wires.The factory microphone requires 5V input in addition to the signal wires. I couldn't find an adapter that made it work, the pins would be in the secondary harness that also contains the Aux In + Rear Camera. The head unit I bought had a mic built into the front of it that works quite well, so I didn't even bother running an external mic anywhere. On my old vehicle, the mic was mounted on the top of the A pillar near the sunshade.
My Pumpkin Auto head unit that I bought natively supports steering wheel controls, so the Axxess ASWC-1 is unnecessary for it, but a lot of the more mainstream brands likely do need that.
