1st MP3 in NH said:Depends on the radio your going to replace it with. Typicaly most factory CD players are actualy better units then any aftermarket peice fo runder $200. Typicly if someone doesn't want to pass that threashhold then a new head unit for less than $200 we be a down grade the only time it ever meakes sense to do it is if a feature is needed such as a preout and for some MP3 capability.
If you were thinking of swapping out the factory radio for a cheap BestBUy Sony POS then save your money.
