We're one (small) step closer to the E53 installation!
I found out today that Eonon released the OctaCore units in like May of this year.

The *one* thing I did not like ab the unit was the response time when navigating the menus. I decided then I would wait in the E53 until the newer units with upgraded specs.
If the estimates on Ebay are accurate, I will have it here next Tuesday. I may even have a line on a buyer for the old one.
I am a little concerned ab the upgrade path. While it makes a lot of sense that I could just plug the new one in, it appears at least the wifi and maybe bluetooth connections have changed from my current unit to this one. This would present less concern on a fresh E53 install, but I hope this isn't a total drag on the upgrade.
