I may be accelerating the ditching of my Dice Mediabridge unit and doing the Eonon upgrade
It appears that Eonon is offering their Android GA6166 shipped from HK for $278
Android 5.1 System 7" Car Stereo DVD Player GPS Navigator OBD2 for BMW E53 X5 E | eBay
Nice that they helped OrangeFurious with a firmware upgrade. In the early days of my E46 GM5150 unit from Eonon, they issued several firmware updates to address user issues.
