Good question, and it comes up a lot. Phones have become genuinely capable navigation tools, but dedicated GPS units still hold some real advantages depending on how you travel.
Reliability and battery life are the big ones. A dedicated GPS draws very little power compared to running navigation on a phone with the screen on, and it does not compete with calls, messages, or other apps. On a long road trip this matters. A GPS unit also keeps working if your phone runs flat or loses signal.
Signal and offline use are worth considering too. Dedicated GPS units store full maps on the device and never need a data connection. Phones can do this with the right app (Google Maps offline, Sygic, OsmAnd, and others all allow downloaded maps), but many people rely on live data without realizing it, which can leave them stuck in areas with poor cell coverage - and there is plenty of that across rural USA.
Durability and mounting are practical points. A GPS unit is purpose-built to sit on a windshield or dash mount in heat and vibration, has a screen designed for direct sunlight, and you are not tying up your phone while driving.
That said, if you are sticking mainly to well-covered urban and interstate routes, a phone with downloaded maps and a good mount is perfectly capable for most travelers. The gap has narrowed considerably. Where dedicated GPS still earns its place is long rural drives, areas with spotty coverage, or if you simply want a device dedicated to the job so your phone stays free.
