Not sure about the most basic system but I have the Discover Media option ZI7 and here’s what I know:
It has 6 speakers and sounds pretty decent when playing media from my iPhone but the standard (non DAB) radio sounds rubbish. (Mine’s German but I think all uk models now have DAB so you may be ok on that front?)
It has speed sensitive volume which you can adjust.
The speakers are A pillar, front doors and either side of the rear bench in my Beach. I didn’t have Apple CarPlay but had it retrofitted in an hour by VW for around £220. Worth doing for me as streaming net radio through the phone is way better quality than the analogue radio and a kind of DAB workaround).
CarPlay also gives you some voice control if you long press the voice button on the steering wheel. Hey Siri also still works.
There’s an SD card slot on each side of the screen. One is permanently occupied by the sat nav map data card and the other is free for Music and allegedly, photos but I’ve never tried those. I HAVE tried movies loaded onto an SD card but there’s no picture on screen - just the audio from the movie - maybe this is down to the format I’d chosen and I’d be interested to hear if anyone’s succeeded in playing movies on it. There’s a CD slot. Never tried it. Now wondering if it plays DVD
There’s a USB / aux connection in the glovebox and this works with iPods AND phones, with control via the 6.33” touch screen or the MF steering wheel if you option that.
As someone previously mentioned, it also streams via Bluetooth showing album art etc, sound quality seems the same as using CarPlay.
It also has VW’s CarNet optioned. This is useful as you can look up a destination on your phone when you’re away from the vehicle and it transfers to the car when it goes online.
I wireless hotspot the unit to my iPhone but seems I have to remember to do this every time I get in the car. It’s used for traffic data and dynamic routing etc on the sat nav.
I reckon this standard set up is pretty decent but would benefit from some sound insulation in the front doors and maybe an under seat sub if you could be bothered (don’t know if it has a sub ‘line-out’) but it’s decent enough for me not to bother with either. I’m not sure I’d want to sacrifice the very useful top centre dash storage for the sake of another speaker.
