I've found navigating by sign much easier by any sign anyhow.
Maps can break down at the most critical points: multiple exits happening in quick succession, exits followed by forks, the GPS reading you the entire sign contents which just serves as a distraction more than anything, etc. Not to mention now there is a screen you have to pay attention to!
If you know where you're going and the general route to get there (i.e. which highway to get onto), following by sign is much easier. Cities are exceptionally well marked. It's a low-tech solution that just works. And yes, no worries about the signs dying or losing signal or crashing.
