My car is a 2001 and has a CD player. Normally, this would preclude playing phone music (without that FM transmitter bullshit, at least), but this CD player was built to accommodate a 6-CD changer in the trunk, and you can buy a little gadget that plugs into the port for this and allows an aux jack to feed audio into the player. This worked great for me until my latest phone which has no audio port. My USB-C to 1/8" jack technically works, but the volume is way too low. So I’m back to burning CDs for my car.

You can get Bluetooth to aux devices so you can send music over Bluetooth. Works great, did that for a long time myself.
I’ve got a similarly older vehicle. I ended up buying a little Bluetooth dongle that plugs into the aux jack for, like, $10.
I wish I had an aux jack. 2001 just predates that, I guess.
Have you tried USB-specific players? I remember using USB player pro or whatever it was called, did the job perfectly.
If you’re going to get BT adapter, may I recommend this?
