2011 Buick Regal
Navigation Unit

This is a remanufactured GMC/Chevy/Cadillac Factory OEM In-Dash Navigation Unit with built in Satellite Radio and Hard Drive made by Denso. These units have a GM/Denso certified UPDATED motherboard that will fix your navigation and radio.

You will need to have the unit reprogrammed by a dealer regardless of the XM radio or not. If you can provide us with the OEM Cadillac part number, we can cross reference it in our system to ensure correct fitment.

Thank you for your inquiry. The navigation on this listing only works on the 2010 Cadillac SRX that came equipped with it from factory. We do not sell navigation units to add on vehicles that are not originally equipped with them.

This unit does not include the NAV DVD. You will need to reuse your disc.

We don't usually carry GPS antennae since they rarely need to be replaced, but if you send us an email via the "Contact Us" link. we can check to see if that's something we can special order for you.

This is a stock replacement nav unit, for vehicles that had this exact unit from the factory, and it has the exact same connections as the unit you are replacing.
