My husband just bought an Alphard 2022 30 series, and he asked me to do some research on CarPlay and 360° camera options — for both the front head unit (the screen between the air-conditioning vents) and the rear ceiling-mounted screen for passengers. I’m honestly feeling a bit overwhelmed because I don’t really understand car audio systems. Any recommended brands?

look for sound stream brand..
a lot of option available for alphard and a lot of them comes with the vent cover or required bracket
u can go for higher end model like alpine if you have better budget

Dynavin , it’s not cheap compared others but best for Alphard out there

Just walk into any accessory shop if u saw dynavin player n ask full price include installation player , crystal clear 360 x 6 camera which include recording

I am driving Alphard 2021 with original player only reverse camera, the sensor around Alphard are good enough for me to go thru tight spaces

There is no perfect HUD ya, be warn... A lot of owners already start regret.. If you dont care sound, radio quality, normal android player with 360 camera is good. If want better sound, radio quality better ask for those from reputable brands like Pioneer, Alpine, Kenwood, etc brands from Japan, expensive but overall radio fm receiving, sound quality is far better than Androids player a lot.
