A: As with most vehicles, you will need a few parts to make this fit your car. You will need the dash kit, wire harness, and antenna adaptor that are specific to your vehicle to house and power this radio. I didn't link those parts because they are specific to your car alone, talk to your local installers for more information or use the Vehicle Fitguide available on the Geek Squad mobile app (android and iphone). To retain your steering wheel controls and satellite radio, you will need the additional recommended products listed below. iDatalink now makes a Sirius antenna adaptor that will work with the SXM tuner and retain your factory antenna, so that you do not have to run an aftermarket external antenna. While this part is not required, it makes for a much simpler and cleaner install.
Q: Is this radio compatible with a 2010 Saturn Outlook?
A: This will work with your vehicle.
A: This does not have a hard drive.
