A:Answer The install price is the same if you buy your radio from Best Buy or if you do not. If you call them and tell them the make, model and year of your car they can provide you with a cost. They will also need to know if you currently have radio controls on your steering wheel or controls that can be operated from the back seat. Aside from their installation cost you will need to pay 16.99 for the installation harness and 16.99 for the dash installation kit and a 5$ material fee. The price for mine seemed reasonable. Best to make an appointment, unless you want to leave your car all day and be fitted in between appointments.
