SUMMARY Original Equipment (OEM) GM navigation radio Brand new Touch-screen navigation system Intended for exact replacement only Includes only what you see in our pictures GM part number 25812385 Match this part number to yours!!! Perfect condition. Still has the plastic on the display! 30 day warranty Returns are not accepted A return request is different from a warranty request See Return Policy section below APPLICATIONS This radio was offered as an option in the following vehicles. But that doesn't mean it fits EVERY vehicle that happens to be on the list. Check your part number and make sure it matches!! They made different versions for different years and equipment options. The Compatibility and Application Lists are just a starting point and should not trump the obvious need for common sense and basic research. Part number DOES matter! Buick Lucerne Super: 2008 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 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. This means it couldn't be sold as new anymore. 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 $5 item, no problem. But not a $500 item. Just make sure it's the same as your part number or your dealer guarantees it is 100% interchangeable and you won't have a problem. Warranty Policy: A warranty exchange is different from a return. If you have a defect within the warranty period (which shouldn't happen with a new, tested radio), we offer replacement with the same part number only. No upgrades, downgrades, credits, refunds, etc. This radio is intended for exact replacement only. (Say, yours was stolen or is defective.) Please don't take a chance on this radio without checking your part number, thinking you can send it back if it doesn't work for you. That's not a warranty claim. Shipping Policy: We ship fast. We provide tracking. (It is uploaded into the system.) We protect the item very well.
