2017 Subaru BRZ - Canadian

Post by SpeedYellow » Mon Apr 09, 2018 7:52 am

I have a 2017 Subaru BRZ. It does not use the Starlink head unit found in the US models but rather the Fujitsu Ten model found in 2013-2015; the steering wheel is similar but does not have the voice command button on the right side.
I have a Kenwood DDX9904s head unit. I have a Maestro RR and the TO1 wiring harness. I assembled according to the website and flashed the RR with the recommended software - RR-TOY01-DS (did this yesterday and used the latest version).
The harness did not have a 16 pin connector for the reverse camera - I obtained the necessary connector and attached the 6v supply and camera leads.
I checked the Kenwood site and updated the head unit to the latest software.
With everything assembled, the reverse camera works (via a front panel button on the head unit) but does not automatically switch when the car is in reverse. It seems like the 28 pin harness on TO1 doesn't connect the reverse sensing pin?
The gauges work.
The steering wheel controls don't map properly - most buttons do nothing, but ">" (skip track forward) raises the volume and "mode" or "Source" triggers the mute function.
Any help or suggestions would be appreciated!

Is your vehicle automatic or manual transmission?

The BRZ is called "Inazuma Edition" in Canada, otherwise known as Series Yellow in the US. It is a 2017 model with manual transmission.

Thanks for the quick response!

On manual transmission vehicles, the rr generally doesn't output the reverse signal because it's not on the data lines. If you hook it up manually you should be ok.

I’m not sure which pins are the same between the Canadian and US 17 BRZ, but I had to add several pins to the 28 pin connector that was included with the T01 harness. Pin 2 provides the reverse signal to switch to the reverse camera automatically (I connected pin 2 directly from the 28 pin harness to the reverse signal input on the aftermarket head unit), pin 9 provides power to the factory amplifier (which I connected directly to the remote/amp power on wire on the head unit), you already have the camera powering on so I won’t bother going into those pins.

Thanks Dara and 17brz - I had the reverse signal working previously on my hand-built harness, I'll add pin 2 (which was unpinned in TO1) and connect it directly to the reverse input from the head unit. The head unit reverse was connected to the TO1 harness but I assume I should break that connection and just go directly to pin 2 on the 28 pin connector.

Hoping to figure out the steering wheel controls as well, do you need me to measure resistance?

Thanks again

Please post a picture of your steering wheel and resistances, if you have them. These BRZs have been all over the place in terms of steering wheel layout.

Yes, I wired directly from pin 2 to the head unit, I am not using the reverse wire on the T01 harness as it doesn't seem to do anything.

I re-pinned the 28 pin connector and the reverse signal DOES now switch the head unit view to the camera.

For the steering button resistances, I used an older ohmmeter and the values seemed to fluctuate a bit. I took this diagram from a previous post by 4ghatch and updated my values in the bold boxes to the left and right. I note that the Seek+ button functions as Volume+; in 4ghatch's diagram the Seek+ button is 117 ohms, in my case it is 30ohms, which is the smallest value. Similarly the Source button functions as Mute, again it is 117 ohms in 4ghatch's case and 20 ohms in my case. No other buttons do anything in my 2017 Canadian Inazuma edition BRZ.
Thanks for your help - Dara will you issue new firmware?

Re-flash. There is a second wheel listed now. It's temporarily added for you, because there is one small issue- there is a button on there labeled as Voice (it is actually your enter/mute button).
