most of my rides are back and forth over familiar territory, but when i go to new places i'd like to not get lost. some recent trips only took 3-4 times longer than they should have... everything from missing street signs and directions that were less than good, to "operator error". a good sat-nav system could have helped tremendously.
what do i need in a navigation device? i think...
* display that works in sunlight
* display that works at night
* works with riding gloves
* audible alerts would be great
* ability to make/change routes without a computer
* 8+ hours battery life
* linux compatibility
* expandability (ANT+) would be nice, but currently not needed
most of all, i want something that doesn't suck. that might be the deal-breaker.
from my recent research, it seems like smart-phones and small android tablets don't have good displays for daylight, and they don't work well with gloves... but the apps are as good or better than anything available in a dedicated unit and they now work well even without cell coverage.
it seems like the dedicated units are expensive, require windoze/mac to use/access all of the features, and most of them seem to charge extra for maps. despite some of the proprietary features, it seems like the actual utility as a navigation system is almost as good as the android apps.
is there anything i'm missing? or should i just sit on the sidelines until a clear winner emerges? right now i don't have disposable income for this type of toy so if i can't get it right the first time, i'd rather wait.
