What is Additive Inverse? 10 points!!!!!!?
Additive inverse is the technical term for opposite. So a5+3. You keep the first number the same, change the - to + and make the -3 a +3. Hope this helps :)
TomTom also makes a GPS specifically for motorcycles, called the TomTom Rider. It comes with a mounting kit for your motorcycle, and also an earpiece and microphone (for voice commands) for your helmet. The instructions are communicated to you so you don't have to even look at the map for reference. You can also purchase a mounting kit for your car, so you can take it with you wherever you go. I wouldn't say this device is any less safe then the other instrument panels you have on your bike, assuming you use it correctly. I've considered getting one, mainly because the best riding in my area is on country roads. It's easy to get lost and find yourself running low on fuel, with no reference where the closest gas station is. A GPS would be quite handy to point me in the right direction.
I find the fact you would like to use a GPS interesting, I have thought about it myself. Only I want to use it to track my rides so I can later download it to my computer and map the ride. I have been looking at just a simple one that will fit inside my backpack or my tank bag. I do agree with the previous answers, you don't need to have the annoyance of trying to fumble with anything else while trying to ride. Is like trying to ride with an MP3 player and not liking the next song. By the way, do you live in New Jersey? I had noticed a lot of GPS's when I was there in 2001.
I use my Garmin Street Pilot III GPS on my BMW motorcycle, a well as in my truck. It is built to be weather resistant, and works well on top of the instrument panel of my bike. I have separate mounting brackets for the bike and the truck, so all I have to do is snap the unit out of one mount and into the other. Most dealers who sell GPS units will also sell some sort of mounting brackets you can use to mount your GPS to your bike.
