Garmin has a line of GPS systems for motorcycles.  They are weather-resistant and come with handle bar mounting systems... https://buy.garmin.com/shop/shop.do?cID=135 style="font-size: larger;">

You could use a automobile version, but most are not weather resistant.  You an buy a mount at pretty much any motorcycle accessory store or online motorcycle accessory site. These guys seem to have a mount for just about every system... http://www.mountguys.com/category_s/78.htm .  To power it most use a cigarette lighter style adapter.  If you need one for your bike, we just happen to have one... http://www.cyclefish.com/CycleFish/gstores/241/ style="font-size: larger;">

As for the visability, most of the nesw motorcycle GPS sysyems I have seen come with built in anti-glare that works pretty well.  And most also have voice command and voice prompts for safety.  Many are Bluetooth enabled also so you can use a wireless helmet communication system to hear voice prompts and give voice command.  I know where you can get a chance to win a helmet comm system that's compatable with GPS   http://www.cyclefish.com/survey_giveaway.php />

Most all the newer GPS's are fine for the glare, and as mentioned, there are anti-glare screens, there are Aqua boxes to make them weatherproof.
A Gps will NOT take you down a dirt road, if you set it right. It will take you down some fun back roads that you would never have taken before. If you do any traveling, they are great and don't take up the room of the maps, and you don't have to stop and read them. It will talk to you and tell you when to turn, and what lane to be in to make the next turn, and what side of the road is your destination and a lot more. Mine is integrated into the stereo so it interrupts the music to tell directions and goes right back to playing.

I use a NUVI and if it rains real hard I throw a clear baggie over it. You can still see it and use it. They are weather resistant, not weather proof. I have been to 49 states and 3 provinces of Canada and never once looked at a map.

Funny thing though...I have had my Garmin 8 years right?  and way back when these things were a lot clumsier than they are now MY Garmin was not just water resistant - It has been out in major storms where it was raining when we started the ride and was raining virtually the whole riding weekend...IT DONT LET WATER IN!!!


ALSO....it has an earpiece socket in it...you put the ear pad inside your helmet and just simply PLUG IT IN!!!


It aint broke so I have no plans on changing it...its just a bit slower than a tom tom but its a darn site more accurate than a tom tom, and they are pretty accurate...oh and did I happen to mention...MY GARMIN IS BRILLIANT!!!!! (even if it is like a fossil compared to new stuff).....


...and just as an information only ..... EVERY Helicopter I have EVER been in has Garmin GPS  fitted.....British Military, British Navy, US commercial and US Civilian.....fitted central in with the rest of the guages.....


Good enough for Helicopters then its good enough for the likes of me...lol...

Thanks to everyone who posted ~ wow, lots of great info! I'm so glad to know that there are so many options. I really appreciate everyone sharing their experiences using a GPS on a bike, we can now make an informed decision on what to get. You guys (and T) are the greatest :-)

Question for the Garmin users

Wondering if it has a function similar to the one on the Tom-Tom

On the Tom-Tom have the option of "Fastest Time" or "Shortest Distance"

The "Shortest Distance" option makes a trip an adventure - Has taken me thru barnyards, down unpaved logging roads, to wooden ferries & attempted to send me over a bridge washed out during the Carter Administration.
Love that option

I have a regular TomTom mounted on a Ram Mount. Has worked great for cross country trips for finding gas stations, hotels ect. as well as regular mapping functions. I keep a zip lock bag and a couple of rubber bands in my bags for when it rains. Got caught in a good old fashion southern thunderstorm in Arkansas and with the bag, my GPS stayed dry and worked perfectly !!!

i have a garmin, its not for a bike because they were close to $750 at the time. i have a shade for it. i have my setting for night time use and at its brightest. i can't hear mine i have to look. when it rains i put it in a baggie. i have it wired right to my battery and it doesnt drain it when i don't use it.

Hey savage...mine is 8 years old now and still works perfectly...and yes it does have shortest, fastest, etc ... but it still is down to how you program it...I have mine set for biggest roads first on a high percentage, then on next size down as main high setting, then lesser roads as a backup...it dont need putting in a bag when it rains, it dont need an anti-glare screen...It does EXACTLY what it says on the tin!!!!!

Agreed! No GPS here either! I don't wanna be found when I'm on the bike, maps are more than enough. Travel as light as you can!!

Savage, A lot of the newer GPS systems even have a choice for "Scenic Route" that keep you off the main highways. Plus if it gives you a route you can select things such as "re-route eliminating I-10" and stuff like that.

I love my Garmin GPS. It has found me some new roads right here in So Cal that I didn't know about!

I use the GPS on my iPhone and it too has shown me some pretty interesting roads.

Just say NO.

When riding keep the Tom-Tom in the tank bad - CAUSE I CAN'T READ THE DAMN THING IN DAYLIGHT -
But while driving that "Shortest Distance" option has taken me place I didn't know existed even after driving past them 50 times
Found me a wooden ferry, directly off of a 4 lane interstate.
