Google that file name and you'll find more info. It definitely works on the 9th civic but I could swear the XDA thread said 10th gen. They do mention checking allow unknown sources which is something that doesn't appear in our settings. I'm a programmer and the guy who first hacked the Pioneer AppRadio. I just can't think of any entrance point to get into this thing.
Here are some awesome links. Looks like the 2015s have no problem:

(2016 USA Honda Civic w/Display Audio / Mitsubishi Electric / Android 4.2.2)
I was able to get the Install option to light up, by doing the following:
Downloaded Aha APK from here: https: //apkpure.com/aha/com.aha.android.app?hl=en
Renamed it to com.aha.android.app.apk
Copied it to USB, inserted flash drive into USB below radio (not in armrest).
I did not tap install because I didn't know how long it might take, and I needed to get back to work. I might try later.
I also tried renaming another APK (Google Maps) file name to com.aha.android.app.apk and doing so did not light up the Install option. So for this model, the Whitelist app/service is definitely using the internal package name and not the file name to validate.
I am wondering if there is a whitelisted package name that is not in use so I can install a modified APK.
Or if there is some way to uninstall Aha and use that because I really don't care about Aha at all.
