USA Gear GPS Vehicle Dashboard Mount with Portable Base & 360 Degree Rotating Cradle Neck for 4.3-Inch Garmin Nuvi , TomTom , Magellan & More Navigation Systems
This beanbag mounting system is awesome.  Simple to  use, easy to store and does not budge even though it is not mounted to dash! The sliding release makes it quick to remove my GARMIN 1450 GPS and put it in the leather carry case i also purchased so I can use in pedestrian mode. I love that the beanbag base can be tucked under the seat, leaving no evidence on dash of GPS!
