I've never tried out the video player myself, but since that tweak is Fiat/Mazda neutral, just use the Mazda AIO, if you prefer that version. The goal of the Fiat AIO was to address unique Fiat characteristics, and once I knew the package was stable and reliable, I've intentionally left my package alone.
I borrowed tweaks from the Mazda AIO, and that is how I got into trouble introducing the ftp counter, that I later had to fix
As the author of Fiat tweaks and the person that started this thread, I'm posting in the off-chance that a reader here may know of a source for tweaking the uConnect 8.4, as not being able to enter a destination into the system while driving is really a major letdown. I kept hearing that the uConnect is the best infotainment system out there, but I sure encountered some flaws and letdowns this weekend.
XM doesn't obtain a signal quick enough to boot to that screen, but FM will boot to the the radio screen, if that was the displayed screen when shutdown. In fact, all of the other entertainment screens will do that.
