"Velcro attaching it to your windjammer will work best, but if you don't want to go that route, you can put in tankbag or pocket and pull it out when you get close. Some people put it into the clear map pocket on tankbag but it doesn't always see the unit there. "

The Maine turnpike authority doesn't recommend velcro'ing it to the windshield as they can fly off. The recommendation I got was: Register your lp with the EZP folks and keep the EZP in your pocket or on the bike somewhere and drive on thru.
