Just to let you know. I have had a "Garmin nuvi" GPS device for about a year. Since it was illegal, at the time of purchase, to mount the device on the windshield in the state of California I purchased the bean bag dash mount holder. This weekend I purchased the "Car Mount Phone Holder" for my Droid at the local Verizon store. Even though it is now legal to mount a device on the windshield (with restrictions) I prefer the dash bean bag. I experimented and discovered that the Droid mount plate fits perfectly on the bean bag mount holder. For GPS directions, I can now interchange the Garmin and Droid to use the dash bean bag mount according to my preference at any given time.
