In short, no.
In reality, yes but you can either do it via cassette adaptor (vile sound) or FM transmitter (slightly less vile sound) or by doing a bit of soldering yourself (haven't heard the finished product myself). Tbh your best bet is just to change the head unit for something decent, it really is the best way forward. I used to have an Alpine system in my car and it was fantastic, but you can just buy whatever fits your budget. Really don't try and do it on the cheap using the cassette adaptor or FM transmitter though, as you're throwing good money away. Do it once, do it properly.
And welcome along!
