Bluetooth in old car

[newbie265]

I have a 2004 polo and want to install Bluetooth to play Spotify. I used to use the tape deck and plug into the headphone socket on my iPhone.I now have a Samsung s20 with no socket, what is my best option a fm transmitter ?
I have no usb port or aux given the age of the car , any voice control and call answering would be a bonus as well as dab radio but not essential. My 6 cd player us built in so couldn't have anything installed in there.

You could use an adaptor that allows for charging and audio with phone support
