I'd look around for a used Garmin Street Pilot 2610 or 2720 (see: http://www.amazon.com/Garmin-StreetPilot-2720-Portable-Navigator/dp/B000A5T7AO/ref=sr_1_1?ie=UTF8&qid=1402996642&sr=8-1&keywords=garmin+2720) . These things were the shit a couple of years ago and still work very well. They're waterproof and unlike most newer Garmin products, they had most of the bugs worked out before Garmin released them. They were far from cheap when new. The screen isn't huge but it's easily readable when mounted on a bike. Touch screen is easy to use, too. I have two of them - one that I bought new and one that I bought used. Both still work great and you'll most likely get a copy of the mapping software with the unit. Map out your routes on a PC and then load into the unit. Or, you can map it out on the unit as well on the fly. Mount: I used RAM balls and arms. Cheap, vibration free and work great. See: http://www.rammount.com/Products/MotorcycleMounts/tabid/128/Default.aspx They even make a cradle specific for the Garmin 2720. I don't; use any bluetooth or speakers in my helmet - just pay attention. It's plenty bright enough to see in direct sunlight, so no worries there. Bets part is the price - at $50 or so, if you get 1-2 years out of it and it craps out; you're not out big $$. A lot of the new Garmin stuff seems to act like a beta version - it never works 100% right and has to be constantly updated. The slightly older units are proven to work well. They shouldn't have gotten rid of them.
