Retrofit Facelift Model (2015+) Head Unit to Pre-Facelift Model (2012 - 2014)

My v is a 2013 and I had the head unit with the navigation (57011) model and hated it. While the thought of changing it to an aftermarket head unit crossed my mind, I didn't want to lose the vehicle settings functionality. After watching youtube videos of the later facelift model head unit in action, I liked how the display graphics were more crisp, it had split screen capability, the touch screen was much more responsive and everything just loads quicker. But that wouldn't justify the cost of purchasing it, even a used one. That was until I came across a salvage yard seller on ebay, that was selling it (510057 model) for just under $200! Which also included the XM tuner module w/ the wire harness and SD card map for the navigation!

Did quite a bit of research, especially on toyotanation.com & tacomaworld.com. Apparently a lot of people retrofit their non-navigation head units with the navigation ones.

Almost everything was plug & play except for the GPS & XM antenna as well as the backup camera. The GPS & XM changed from the square FAKRA connectors (Blue and Grey) to something more U-shaped. The backup camera connector changed from a 16 pin to a 24 pin. Not sure why Toyota did that, since the backup camera only uses 5 wires...

Pre-Facelift

XM antenna - blue connector (upper right corner)
GPS antenna - grey connector (lower left corner)
backup camera - top middle connector right above the grey square connector (USB)

Facelift

XM antenna - dark grey connector (lower left corner)
GPS antenna - cream connector (upper right corner)
backup camera - top left connector
* The new head unit has a unused socket that sits between the 24 pin backup camera and the 28 pin. Not sure why

So the adapters I got were 2x 86808-02080 priced at around $35


These are GPS adapters made for the Corolla that allow you to connect the square FAKRA to the U-shaped connector on the newer head unit. It wasn't a clean fit on the XM plug since that's a separate part on its own (86101-02550) but you can gently force it in, until it clicks (the GPS and XM connectors have different grooves). The XM adapter costed about double of the GPS adapter. I didn't want to pay more, so I took the risk and thankfully it worked!

For the backup camera, I found a online vendor (AutoHarnessHouse) that was able to custom make a 16 pin male to 24 pin female adapter. Brands like Scosche only makes adapters that connect to aftermarket units.


I'd like to note, when I connected everything, I was quite frustrated that the unit didn't detect my GPS antennae and the XM radio kept cutting in and out with very little service. It bothered me for weeks as I kept wondering if the GPS adapters were faulty or just wouldn't work for the Prius. It turned out, the XM and GPS connectors got swapped on the newer head units.

Lastly, I decided to also pickup from the same salvage seller, the climate control / AC unit since it was redesigned just a little to look more flush with the newer head unit. The center air vents would also need to be replaced to give it a cleaner look, but I can live with that for now, until I find it on ebay for cheap.

 

Yes I did. Steering wheel and voice recognition still functions. The head unit properly displays my MPG history and status updates. And it also gave me additional options (can't remember off the top of my head) in "Vehicle Settings"

 

The head units I swapped out were NON JBL. You are correct, ONLY the HU from a v will fit other v's. The facelift model # designations are as follows for USA:

510058 - JBL
510057 - NAV
510056 - NON-NAV

Seeing that you're from Amsterdam, I found this site that has the part/model numbers for the European Plus
