alright guys so i finally got the steering wheel controls installed along with my carbon fiber steering wheel.

"http://s280.photobucket.com/user/blazing-55/embed/slideshow/

the controls work! Now everything is working as it was designed. as you can see the plugs are pretty much the same thing.

for the pic with the pink wire that is the starlink cable. all i did was move the pin to the first top left plug as you see. then i inserted the 8pin plug to the 12 plug behind the radio. (i know its not the same plug but it went in and it did the job of connecting it added some tape behind so it would not fall) I could not find a 12 plug anywhere so i could clip it in correctly but it worked. at
minute 18:16 he shows the plug. the blue wire is star link so that is what i did to match it.

so all is left to do is find a way for the radio to shut off after door is opened/closed. I read that the body integration ecu has to be replaced part# 88281-VA850. it cost about 221 bucks but defeats the purpose of the swap, I paid 250 for radio and 120 for steering wheel switches. If i find a cheap ecu Ill install it and get back to you guys. For now 3 minutes for it to shut off is not a big deal

every plug is plug and play including rear view camera
the pic with headunit from behind with yellow circle is where i plugged in usb cable works. both work. the red circle for plug is the star link plug i was talking about

I just bought one too for my forester, does your car also have the 2 usb ports right next to the aux and if it does did you try the aux yet, it looks good man.

Your old radio does not have the standalone connector for the backup camera so it should not work and that connector would be i146 in the service manual. Your car has the backup camera on the 28pin connector i192 instead so you're right about that car needing a harness..

Just Tried it on a 2018 Forester and from what I see

USB/AUX works
Android Auto/Carplay Works
Dimming works
CD Player works
XM works (complained about antenna but worked anyway)
Bluetooth works
Backup Camera works

Pretty much everything works besides the radio takes about 3 minutes to turn off and does not turn white like snakes but actually stays on which I prefer VS stock out and the steering wheel controls(which I will fix later) I did have the starlink problem like blazing but the same fix works fine.

I'm going to reinstall it and leave it in once I get my arduino to remap the steering wheel controls because the sound quality is better in my car VS stock.(with my kenwood speakers it is) I's really a shame subaru does not offer an option to just get this as an option because if you have a WRX all you need to do is swap the switch and the starlink connector any it will work besides the 3 minute problem which I think most won't care about anyway.(subaru can probably easily fix this)

Is the "body ECU" different from the main ECU? If they are one in the same then the swap may not be simple. My idea was just to try grounding or supplying power to the door wire. Grounding I'd probably use a door jam switch, and if it needed power the dome light. https://www.carid.com/2000-dodge-neo...yABEgJB7_D_BwE

Where is this starlink connector?

Great work by the both of you and much appreciated for documenting!

Yep I thought of grounding it already and tried it and it worked to turn the radio off.

If you look at the diagram below you will see that the door switch is connecting to the connector i272(12pin on back of radio) from the body integrated unit. I tried on a bench to disconnect power from the acc while constant was connected and the radio stayed on and then turned off in 3 minutes. Grounding out the pin on the back of the radio(i272) while its running off constant turns the radio off. I am hoping simply connecting it straight to the switch(the harness for it is under the drivers dash behind the panel) will turn off the radio with the door open bypassing the body integrated unit.(but that will make it only turn off with the drivers door probably) Now if ground is left on that pin for the switch then the radio will turn off when the car turns off but I don't think it was designed for that.

Dome Lights might also work.

Edit:
I'm going to reinstall mine and leave it in, the stock radio is crap and I'm getting in another Arduino today.

Oh the starlink connector. On my car I have an 8pin connector and the 8th pin on it connects to the telematics unit and if it is left unplugged my starlink will throw an error. To fix mine I looked at the service manual and saw that on the 2019 subaru moved that connection to the 28 pin connector(i87) and that is pin 24 on that connector and if you take it off the 8 pin and stick it in there the starlink light will go green like normal.

Another Problem I noticed is that on mine when the car is turned off and turned back on and put into ACC the radio won't start until you start the engine. The only difference I can see in terms of power is that my car does not have the IG ON on it's i87 connector(the 28pin one) where as the 2019 WRX does. Also when using Auto when you turn the ignition off completely it will cut it off and kick you out of android auto even though the radio will still be on.

Thanks for the extra details. This thread is going to be incredibly helpful when I retro-fit my car hopefully sooner than later.

Its working out pretty good besides the acc and steering wheel switch problem(I was sent the wrong digipot(100k) so I have to wait for the right one)

Default 2018 STI HK System to 2019 Apple Car play/HK swap?

So I own a 2018 STI Limited with the HK system, I desperately want the Apple Car play functionality and OEMness of the 2019+ systems which offer this. I've read through this thread a few times and looking for details on has anyone actually been able to do this? Someone made any adapter harnesses or have the part numbers necessary etc. I'm fairly well versed in 12v electronics but hoping someone has done the heavy lifting of figuring this out or if it's possible or not.

^ no one has posted the back of the HK units of the 19+. Iíve been waiting for some info since this thread started too lol. Iíve given up tbh... the cost new is prohibitive here in Canada, and donor wrecker cars/units are much harder to come by than in the US.

Well if you figure out how to get it done let me know and I'll locate a head unit for you and ship it

Well the first step is being able to see if the connectors are anywhere close to the existing setup for pre-19 HK models. But i guess no HK 19+ owners haven’t switched their units, or don’t care to help us out lol.

And I appreciate the offer, but it’s harder for US cars with the starlink connected services which we don’t have up here in Canada. I wouldn’t know what to do with that. Aside from that, I suspect it should all connect the same and need their steering wheel controls as well since the button resistances are a little different. We may also need the USB module... I’m pretty sure the 19+ has stronger output than our USB, unless the MY18 got upgraded already. We would have the same issue of the unit not shutting off when the car is off since we don’t have the open-door-cutoff too.
