Hey, how did you obtain the update file? I’ve been trying to probe an Acura head unit from the same year, it’s also on Android 4.x, but have ran into a roadblock when it comes to obtaining an update file.
A number of other cars' infotainment systems are also based on ASOP. I remember downloading updates for my Hyundai which were also essentially Android images
The head units themselves are very dated and simply could not run recent versions of Android. I have a 2020 and I'm always eyeing up the after market units which are all better in every way.
