Hi - I want to take the GPS from my car and quickly mount or remove it to the top of the gas tank as needed (I prefer not to mount it to the handle bars because I want to keep the handle bars clean and free of clutter). Does anyone know of a Velcro type (for quick & easy installation/removal) of accessory holder that can be wrapped around the fuel door? (you know, open the fuel door to install/remove the Velcro wrap-around-fuel-door holder and then close the fuel door to keep the holder in place while riding)

Has anyone seen anything like this or have another idea? If yes, please send me information, a link, a pic, etc. Very much appreciated!
