My regular Euro 6 is in the workshop, I’ve been given this Euro 5 and I can’t get my iPhone 8 to work via USB. I’ve managed to dig out my old Pixel that still has a 3.5mm jack so I can use that. If not, might be worthwhile investing in a good quality Bluetooth speaker.
You can also get Lightning-3.5mm adapters, including ones with an extra Lightning socket so you can listen and charge.
