Opinions on the Sony XAV-AX1000

Does anyone have first hands experience with this system? Thinking about getting it but I have a few questions. On startup, does it take long time to load up? Im picking this system specifically for the volume knob and CarPlay. Also CarPlay, does a take a noticeable long time to load up once my phone is plugged in? I know this is an older system and for the same price I can get a the AX3250 which is newer, bigger screen, CarPlay and android but, no knob. Also the brightest, is it bright enough to see google map in daylight? I commute about 1.5 hours to work everyday and I use google map for traffic.
