I got mine WITH NAV for many reasons, but mainly these. I LOVE
the integration of the factory installed, over any aftermarket options.
None of which, in my opinion, look good once installed. Integration, Integration, Integration! I know people will argue about the quality, but for my means it is excellent. And just like real estate...Location, Location, Location! And in my opinion you can't beat the location of the factory unit.
Notice the emphasis that this is just my honest opinion.
