Pros
Screen very clear, touchscreen works well
Android Auto is superb, really very very slick, lots of app support (Google Music, Spotify, Google Maps, Waze and more)
Minimalist design which i like
Great sound quality
Very good video and audio format support
Cons
Startup nag screen (this is a huge issue for me, losing it 2 stars)
Only 1 USB port
No fast charge from USB port
No support for playlists (m3u, pls)
Embarrassingly bad USB playback modes (shuffle whole device, repeat track, that's it)
Slow to boot up
1990's file system support (FAT12!! FAT16, FAT32, that's it, no EXT4, no exFAT, no NTFS). Windows 10 can't even format a large USB disk in these ancient formats anymore, they are so old.
No Google Now/Siri from PTT button when connected via Bluetooth (totally possible, my old Pioneer unit worked fine, this one says not possible!!)
Abysmal Sony UK support (got binned off to a 3rd party for "support" after a have you tried a factory reset response). This lost another star. Sony sell this, i expect you to know about it and support it.
NOTE: i originally had a Amazon warehouse product, the previous "owner" had switched the item in the box and returned it, it was a cheapie double din Sony unit, be VERY wary of warehouse "deals" on this item.
