There’s a whole host of head units out there. Are you after something in keeping with the looks of the zed?

Some food for thought
but all of those will stream to an iPhone but you will have to do some more reading on them if they play well through a usb cable to lightening cable so you can charge and play.
I run an old Alpine CDA 9887 with the old iPhone connector that plugs into the unit via usb and run and second gen iPod . Interface a bit clunky compared to modern stuff but plays the tunes ok. Will be looking to upgrade somewhere down the line.
