crankshaft VS foxy-droid

But, according to : https://github.com/opencardev/crankshaft/wiki/Android-Auto-Wifi

It's pi focused apparently https://github.com/opencardev/crankshaft/wiki

3)The route that I ended up going was to build my own unit with a Raspberry Pi running Crankshaft to run Android Auto and a 7" touchscreen that I mounted magnetically to a phone mount that inserts in the CD player. Doesn't look OEM butif you manage cords it looks pretty clean and works well. Also cost me under $100 and I can remove it easily any time I want. I'm a little techy so it wasn't too hard - there are tons of videos out there that will walk you through the project.

Your other option, which I actually use in my R56, is to utilize the Crankshaft project with a Raspberry Pi and a generic 7" touchscreen from Amazon. I mounted mine with a magnetic mount from the CD drive and power it through the aux power port. Mine works both with wired and wireless Android auto, with very few glitches. If you're techy at all it doesn't take long to set up.

I use an app called Droid-ify

Fennec is different in other sites with different icons , https://www.apkmirror.com/?post_type=app_release&searchtype=apk&s=fennec , https://github.com/kitsunyan/foxy-droid. I do agree Mozilla is par slow in android browser development.

FOSS Store (fork of Foxy Droid) for checking updates.

I always feel a need to recommend the Foxy Droid client on posts complaining about the official client.

Also, when I was F-Droid or Foxy Droid to install APKs it doesn't open them up in package installer, I usually install and update APKs via Foxy Droid https://github.com/kitsunyan/foxy-droid

Yes, the app hasn't been updated in almost a year, but it works perfectly fine. Regarding the project, the dev hasn't abandoned it & you can check his response here.

Foxy Droid might not have received updates in almost a year but that doesn't mean it's abandoned.
