I tried to post this before but I think that I hit the wrong button.
I have a 2002 S60 with the factory radio (I think HU-613), CD and cassette.
I want to add an AUX port. I see a few options.

The second is by getting a used Volvo radio at the junkyard for $20 but I don't know if I'd have to change out other parts if I did that.
The third would be something like this https://www.ebay.com/itm/Yatour-YT-B...-/272223078887
