I almost pulled the trigger on doing this head unit upgrade on my '17 Forester XT but swapping out the amp is holding me back. I can't find one less than $500. Everything else I was able to find for a reasonable price except that.

I did my MY19 Map (built august 2018) radio with ACP & AA with HK amp swap over this long weekend and have pretty much managed to do it but there are some issues.

I purchased the USB 2.1A module and cable from the original wreck and found that mine worked straight up but the USB port I THOUGHT the connecting cable went in (there are three USB ports in the back of the HU) and I swapped it to match those little lugs that differentiate each port. I now have it in the third one to the right looking at the rear of the HU, This may be assigned AUX. I had connectivity with a generic iPhone cable once I realised the little lugs vary on each of the three USB rear inputs. Id connect some extra 2.1A USB's to the inside of the Lift up arm rest too but not sure if this USB connecting cable is available in a longer length?

Steering wheel control are a disappointment as they re mapped with all different positions mostly seek left right dominate volume, and now volume is the Index and Back button to the right of the button array on my model XV. Protivakid let me know if you ever decide to re write the code for that Smart box you mentioned. Or I decide on a complete WRX/STI steering wheel that matches the head unit MY.

The same type of Steering wheel for the MY19 WRX STI

The switches work be sending different resistance values that the radio interprets into commands. My idea was a middle-man box to listen for these values and send the appropriate new value to the radio. Not sure if I'll ever get time to do it but perhaps someday.

It looks like your 2017 crosstrek steering wheel is indeed different. A pic of my 2013 wheel can be seen here: http://www.cars101.com/subaru/crosst...strek2013.html

If you compare this to the WRX wheel the switch footprint is the same so the switches will swap between the two. Unfortunately, unless you can find switches from another model that fit and happen to map values correctly (would be a lot of trial and error unless the FSM lists values, I can check later) you may end up having to swap the whole steering wheel to a WRX wheel if you wanted the switches to behave. I just got used to what Vol +/- was and it hasn't been an issue.

I'm not sure what the other two usb looking jacks on the back of the radio do, I just plugged the one usb cable into the keyed radio port it fit in. Making an extension cable wouldn't be hard though, it's only 5 wires, just cut an existing one and solder/splice in some new longer wires.
