The Google Maps mobile app on iOS/Android has really improved in the last year or two, especially since Google acquired Waze, the crowd-sourced accident/traffic data company. Several times I’ve been using Google Maps to navigate to a spot an hour away only to have my route changed due to traffic and in at least one instance, I saw a small detour for a recent car accident save me easily 30 minutes of traffic time.
The level of detail in ever-improving maps plus the networked information about real-time accidents and traffic is something no car-based GPS navigation can come close to. If you’re car shopping, skip the navigation options entirely since the phone you already have in your pocket is more capable than anything being sold in a car today.
A Whole Lotta Nothing 
Matt, I think the car makers are finally figuring out (with prodding from Apple and Google) that phones are a better solution to navigation and entertainment than the built-in systems – Apple CarPlay and Android Auto are both good moves in this direction.
