Just as an alternative, I use my phone in the car (a Mk1) and fitted a new stereo with digital radio and phone link. However when the hood is down, which is most of the time, it is still rubbish - especially using the phone hands free and the CD is not playable as it skips - so I was using music streaming from my phone which was better.
I have instead started using ear buds (mine are Sony and very comfortable - but DO NOT try skiing with them - you can lose them!) - which connect to my phone. I listen to music and when I have been on the phone, it was apparently a lot better for the other person as the background noise was reduced.
In all, the sound is great, but you are a bit in a bubble, so I am not sure about the safety of them as you do not hear outside noises as clearly as listening to a regular stereo. However I do realise that this is not for everyone. I am also only in my mid 50’s, so still young…
