I just bought a beautiful 07 Tahoe - extremely happy with it. I'm curous if the Nav is OEM though. Only reason I care is that it has extended warranty and curious if that is OEM for coverage, etc. The Nav is Eclipse brand. Did Chevy offer that, or do they use their own GM brand Nav. It looks amazingly stock, clean install etc. It also works with an overhead drop down screen for the second row psgrs, that also appears stock. Does anyone know if that is stock or aftermarket. Also does anyone know how to obtain a list of original equipment for a vehicle? Thanks

Eclipse is not OEM equipment on Chevrolet. However, I am not an expert on the 2007 model year Tahoe. Your best bet is to post your build codes found on the build sheet sticker in your glove box.
