Garmin on the bars, dumbphone in me pocket. Never needed more than a glance at a decent map to get me where I'm going (or Quo, which I have on the pooter at home for SAR work, the entire country in OS 1:25,000). I have a twat nav in the car, but tend only to use it to home in on the last few hundred yards, and use my vast and awesome memory to get me there having read a map beforehand.
A fiends lad is autistic, and only needs to glance for a second at a map and can navigate anywhere from memory. Even things like London Underground maps. I'm not quite in that league, but I'm good enough to be a bit 'gifted' in that department, for want of a better term.
