Indeed my first ever android head unit came with it installed it did use pongo skin from 2019-12, thats how I discovered igo, which led me to this forum because I had to do a full factory reset on the unit and lost the original version that came installed. I have on many occasions attempted to find the pongo skin from 2019-12 but can't find any working links, a shame as I feel it would be worth trying an older version
