What fits into a 2001 Mustang and what is a good system? If anyone can help me it would be greatly appreeciated

 

Go to Crutchfield and click on what fits my vehicle. Itll ask you for year, make ,amd model. Then go to In dash Navigation and they will list the brands that will fit your car. Pinoeers are awesome but the safety features a little too much, requiring you to park everytime you have to change your destination and its hard to bypass when you want to play DVD's while moving (passenger wants to watch). I recently installed an Eclipse and Im loving it.
