Buick Lucerne: 2006-2007 ADDITIONAL INFO We don't give extensive details on the features of this radio because, if you're ordering this radio to replace the same part number, you should be familiar with the features. We advise you to check with your dealer if you have any concerns about features, applications or special installation considerations. Return Policy: Returns are not accepted. Why? Because we've marked this WAY down. Plus we found people often experimented with navigation upgrades without doing the appropriate research. Then the returns had usually been bolted in the dash, which left mounting marks. Plus the radio was often scuffed up and/or had the protective plastic removed. Finally, the radio was often not shipped back in the same manner we shipped it. We protect our radios VERY well for shipping but we often got them back with inadequate protection and/or in under-sized boxes. We simply can't take the chance it will get back here damaged. If it was a $2 item, no problem. But not a $200 item. Just make sure it's the same as your part number. Warranty Policy: There is no warranty. We've marked a large group of these blemished nav radios WAY down to get rid of them. Shipping Policy: We ship fast. We provide tracking. (It is uploaded into the system.) We protect the item very well.
