I turned both up to the max and got much better volume, it was a bit loud, so I adjusted the BMW volume down slightly so I will have a bit of headroom when traffic noises are high. I left the iPhone vol at max (it stays on this setting).

So know I have good volume, but not much room left to boost it higher when needed.
