Great thread Prop
I'm an early Android adopter with the Eonon GA6166 that had a puny 1GB RAM PX3 SoM (System on Motherboard) with Android 5.0. I upgraded this unit to a more robust 4GB RAM PX5 SoM from WITSON on Ali Express.
I highly recommend that any Android head unit buyer not consider anything less than at least 2GB RAM. With basic apps running on my original 1GB system I was near 80% utilization of RAM and app response was very anemic.
My 4GB system is very snappy with however many apps I want to run.
Also, the iBus app and USB stick hardware is a must have IMHO to preserve and improve access to the OBC and offers minor coding functionality.
I would encourage anyone thinking of the upgrade to buy as much head unit as your budget allows and even stretch a little because a subsequent upgrade could mean dragging that long FAKRA cable from the spare tire all the way to the dash all over again
, which is not a pleasant exercise.
You'll also greatly benefit from speaker upgrades with your new head unit and search will give you threads on great ideas from Xoutpost on successful speaker upgrade selections.
