Actually last year when I was new with my bike on delhi roads, I used my GPS extensively. I used to keep it in pocket and listen to it through headphones. Then never really got any chance to use it because those were the days when nokia and navteq were still developing the maps for India and only 4 metros were included in their service. But now the situation has changed and PAN-India is now included. I'm planning to fix it just above the tank pad or above the fuel cap. I really want to do many tweaks in my beast to customize it. And the two cigarette chargers will never harm

. Its good to have a backup. I guess n95 doesn't adjust to brightness automatically. So, increase to brightness to maximum make it easily visible in the sun.

thanks mate for the solutions. You can always use waterproof zips available in market, and for the heating issues and the dust i can suggest make flaps on the side of the bag with using zips and inside place a thin cloth. like momy's chunni

...and during heavy rain you can zip the flap back to its place. Make sure you keep some ventilation in the bottom as air supply is very important.

. I hope it helps.
