Do I have to get an adapter for my 2002 Chevy Malibu or will it come with this item?
Daniel A on Mar 2, 2015
Best Answer: You will need to buy a harness adapter, an antenna adapter, And, if the car has steering wheel volume control,
You will need to buy a compatible steering wheel adapter. I recommend Metra products because they are easier to use, and made in the USA. (note: a lot of times this website will have a promotion to give you the harness adapter, antenna adapter, or the install plate for free. their prices on the other items needed are competitive, and they have a compatibility tool to help you.)
