Replace stock head unit or not? mp3
Another solution would be a trunk mounted MP3 capable changer, portable, or MP3 player, running through the AUX input of a compatible factory deck. (though avoid FM modulated or NEO changer designs, they blow).
If you can afford it just get a basic aftermarket deck and be done with it. A lower priced model is not a huge target for theft and can look perfectly clean in the dash.
