Radio Replacement 2006 LS

Have a 2006 Ende LS with the stock, terrible radio. I would love to upgrade and add an input for an aftermarket satellite radio. I done this before, but the LS is a big challenge. Anyone out there do it?

I just got an 2006 limited edition and have the same problem. Did you find a solution ? i see they sell kits for this model online but i don't see how they would work on the endeavor
