A motorcycle GPS unit will mount to your bike just as easy, if not easier, than a car model will. For more information on this subject please refer to the link provided http://www.garmin.com/garmin/cms/site/us/ontheroad/
The GPS navman does not come with a car mount. But a car mount can be bought at almost any electronics store. http://ukstore.navmanstores.com/Accessories.htm
If you are riding on a motorcycle, you should be paying attention to the car in front of you. If you look at your GPS, you could crash into the car or something else.
Motorcycle gps mounts are a great investment. You will need to find one specific to your motorcyle. I recommend going to your local motorcycle dealer and find what suits your situation.
A bean bag mount is not the preferred way to mount your GPS in your car. Look instead for a more standardized adjustable mount, with several points of articulation.
You can learn about the best GPS handlebar mount on the following site: http://www.webbikeworld.com/garmin-gps/garmin-gps-handlebar-mount/. They are definitley useful.
You can purchase a GPS car dash mount from Best Buy, eBay, Amazon, Walmart, Target, and you might even be able to get a GPS device installed in your vehicle.
If you need a mount to mount your Garmin GPS to your car, try a nuvi mount or friction mount. For more information, be sure to browse to http://www.mountguys.com/category_s/29.htm or even http://www.gpscity.com/gps-mount.
Assuming you are in a car or on a motorcycle you can get a GPS device put in the car and program it to record where you go. If you are on foot and yourcellphone has GPS you can download an app to track where you go instead.
I can be used but it is not preferred as the car device doesn't fit on the motorcycle as well and the voice instructions would be difficult to hear. They do have a motorcycle version but it is slightly more expensive.

Just like in cars, GPS units are produced for motorcycles. Any kind of accessory for a car or motorcycle can be dangerous if not used as directed. If you follow the user instructions, and use a little common sense, a GPS used on a motorcycle will be useful, instead of deadly.
You mount a garmin gps on your bike by first, picking what model you c=want to use first. You then build a complete mounting system for the gps to go on. Lastly you simply out the gps on the completed mounting systemhttp://www.ram-mount.com/Products/BicycleMounts/tabid/3303/Default.aspx
Yes, a motorcycle GPS mount should definitely be waterproof. Otherwise, they wouldn't be of much use in wet conditions. This may depend on the brand, so make sure you check before you take it out in the rain.
