GPS Magazine Excerpt
"The friction, or beanbag, type mount may not look as sleek as the windshield mount, but local laws and/or criminals may dictate that you use one. The mount can easily be taken off the dash and hidden under the seat when parking. Plus, you don't have to worry about melting the rubber mount in a hot parked car."GPS Magazine: Don't Like the Windshield Mount?... (August 17, 2007)
