Aux in/Bluetooth on a 1999 328ci?

Hi, I‘m pretty close to buying this 99“ 328ci and was wondering if it would be possible to make the sound system work with my phone.

An Aux port would be perfect, but I wouldn’t mind Bluetooth either.

There is currently a standard cassette player installed.

I’m hoping to not change the visuals of the infotainment and make it look as OEM as possible.

Thanks :)
