Katuzo, I took some real nice pictures of my GPS setup. If you want, PM me with your e-mail address and I'll send them to you. I don't have any vibration issues with my GPS setup. I would not feel comfortable mounting anything to the gas tank that requires drilling. With the handle bars, it is mounted to metal and not plastic which I feel would cut down on any vibration. Another thing, I've had four Garmin GPS's and loved them all with no problems. I had a friend with a Magallen and he threw it into a canyon. Now that was years ago so they might be better now. Even though I have my GPS mounted next to my spedo, it has a pretty small screen and I need to slow down and make a quick glance at it. My GPS has a page with large numbers. If I'm trying to GO TO a waypoint, I put it on that page and I can see the arrow and digital speed even while travling fast, In fact I use the GPS's digital speed instead of the ATV's spedo because it's easyer to read. The map is real hard to see unless you're stopped. My pictures will show what I see while sitting on my quad.

 

I think I got some pictures up...

 

I wouldnt drill into the gas tank either. My fab was going to be w/the gas CAP. It would be easy to do.

 

I have pics of the Ram mount...its very study and after 900 km the gps is still doing fine with the vibrations.

 

you mentioned that you modified your bushguard, what did you do to get more protection?
