Dedicated GPS

A conversation was struck up at work about GPS -- is a phone good enough? How about on-board nav?I have to say that I'm partial to a dedicated GPS unit. On a motorcycle doubly-so. A device that doesn't really try to do a whole lot more than provide a good navigation interface lets it concentrate on getting the navigation done right.A phone's core competency is accessing Facebook and email. Oddly, it's likely not a phone for most people. If the map sucks, well, what ever. (See also: First generation Apple Maps) When I fire up Waze I've not had audio from it for the past month -- it borders on useless. That's not even to talk about generally needing a cell network to use it. (Sure, you can download a bit of the map, but once beyond, you're screwed.)My car's use is to get me places. Subaru bundled a nav system. The nav system is, at best, an afterthought -- and that's being generous. Again, a system which isn't going to stop someone from buying the device. A car in this case.That brings me back to the GPS... if it doesn't work I'll return it.Garmin, IMHO, does a great job at it. I keep buying them. They just seem to work.For me at least.
