GPS navagation is a good thing. I use a Tom-Tom 1 now 'bout $125, made for the car not a bike, but still find it handy. I think GPS is going to go the way of the calculator, everyone will have them, and the price will be in the $50 price range. While the Tom-Tom works in a pouch on my bar, it is by no means perfect for an HD, but again it just plain works.
Wish list made for a bike should provide 1) Loud volume, 2) Bright display, 3) Rugged design (drop & water resistant), 4) User storage of personal favorites optimized rather than recalculating each time stored in a memory stick by user instead of only extra maps & 5) Blue Tooth (wirefree) interface if you want to integrate to your on-board electronics, i.e. wireless headset/cell phone, Blackberry, XM/Sirius/Itunes or similar etc. (for those of you who ride a feature rich bagger). :newsmile020:
Yes you can do fine without, but why...ever get lost, or end up on a dead end road? :devil
Again, new technology is good, only as long as used in moderation (always try to minimize distractions and concentrate on your riding) and have a low tech alternative backup (address book, health card, and maps are a good thing).:57:
