- Only supports Android v9, v10 was released 9/2019
Typically a manufacturer only states support for the version they tested with. If newer versions of Android, lets say for arguments sake, Android 11 breaks the phone-Uconnect interface then Uconnect will find the issue, write a patch and push an OTA update. This is industry standard.
- Only supports flash drives up to 64GB, formatted FAT32, this is out dated by 5 years
Again, typically a manufacturer only states support for the version they tested with. Apparently that was 64g. I havent tested it yet but the USB will likely support at least 500gb if not 1TB. It has more to do with the maximum capacity of the standard. Have you verified that your flash memory is genuine and not counterfeit?
As far as FAT32, that too is pretty standard for the industry. How does that limit your use?
- Supports mp3 only, again, 5 years ago
I don't doubt you but I'll test some other formats, I've only had the 12" Uconnect for 3 weeks.
- No browsing over Bluetooth, that's AVCRP v1.3 again from 2015
Browse what, the Uconnect Disk? Why would any OEM allow that? I haven't tried it yet but can you not see Artists and albums and songs on your flash media?
- Will not allow you to use vehicle GPS when using Android Auto.
So write them an email with a feature request, if they get enough people requesting that they may implement it.
