Well, to be perfectly honest, I did have the opportunity to get this model car without a GPS, if I were willing to lose a lot of other features with it and special-order it from the manufacturer.
The maker only offered the advanced "Safety and Collision-Avoidance" features as part of the "Technology" package that also included the NAV system, an upgraded audio system and heated seats. The tweeters are nice, but trust me, I really don't care about having a built-in GPS or heated seats. (And satellite radio. A complete waste with all of the tunnels and parking garages and tall buildings that I have to deal with.) Round here, an alarm that sounds when the driver next to you starts swinging into your lane without a signal is priceless.
And on top of that, no dealer in the region stocks that model vehicle without the Technology package, so if I were okay losing every safety feature of the car that made it worth the premium price just to ditch the GPS then I'd have to find a dealer willing to order one for me and wait up to several months for it to ship from the factory.
Between the two, it just seemed better to take the silly NAV that they were throwing in.
I use Waze for navigation. A 3rd party magnetic mount on my dash holds my cell phone at the perfect spot on the dash, above and to the left of the steering wheel where my peripheral vision catches it and I don't have to take my eyes off the road.
The built-in GPS is roughly centered on the dash below the windshield. Very hard to see without turning my head and looking down. And with roads constantly changing around here for construction, it's not really useful at all.
