A garmin portable friction mount is fairly economical at around 15$. You can buy them anywhere, but there are some on amazon. http://www.Amazon.com/Garmin-010-10908-00-Portable-Friction-Mount/dp/B000LRMS66
The Garmin navigation system that comes with the most maps would be the Garmin Nuvi 2455LMT 4.3-Inch Portable GPS. It has the most maps of all the GPS systems.
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. Here is the link for the Motorcycle navigation. http://www.gpsnavigatorsreview.com/garmin/garmin-zumo-550-35-inch-portable-gps-motorcycle-navigator/
Garmin Forerunner 305 Handheld / Trail GPS with Heart Rate Monitor because you wear it like a watch
The place to start would be the Garmin web site which has the Garmin voices available. The Garmin forum will also have information on Garmin voices available.
Garmin is one of the largest manufacturers of portable GPS devices and so it can be found at almost any electronics store or big box retailer which has a presence online. I would personally recommend Amazon.com as a good place to go.
All expeditions that go to Mount Everest take there own portable generators with them which gives them electric at Base Camp.
According to several reviews, no. The Garmin Bean Bag Mount has a non-skid underside and is heavy. It seems to be best used for temporary travel so if you are looking for a permanent solution, a plastic mount would be better.
Garmin are available at most electronic stores. This would include the online retailer Amazon, Best Buy, and Conn's. It would also be available directly from Garmin.
I would go directly to the garmin website. They can offer you tons of information about the Garmin Outdoor including it's features along with specifications.
There are a couple of websites where you can purchase a Garmin running watch. The best place to check would be Garmin's official online website store.
Unfortunately, Garmin does not offer a Golf Course GPS package for the Garmin Model 205W. You would have to purchase the Garmin GolfLogix GPS unit.
If you are in the market for a Garmin 205 you can purchase one at you local best buy or radio shack. If you would like it sent directly to you, you can opt to buy it from Garmin or Amazon.
