You can prolly get by with velcro, but it's the velcro used by EZ Pass transponders and adhere's to a cars windshield. If it can stick there, it'll stick to your dashboard. If you have EZ Pass, call them and simply tell them you need 4 extra strips and within a few weeks, Volia! they send them free. That stuff is true 'hook and loop' velcro. Once on the dash, good luck removing it.
