ELI5: Why GPS in smartphone reports better accuracy than dedicated GPS navigation.

I noticed that in the city, a smartphone can report awesome accuracy (<3 m) but a regular tourist navigation (Oregon) report more than 7 m. Shouldn't it be in reverse?

Your phone doesn't just use GPS, it also uses cell tower triangulation and Wi-Fi networks to get better accuracy. You don't even need to be connected to Wi-Fi, as long as your phone can detect the networks, you can use it to find your location.
