Our readers and customers always give us great ideas for new products. We were recently asked how to use a car mount used for a GPS in the car. Why would you want to do this? A few good reasons. As we all know, smartphones including the Droid and iPhone have excellent GPS capabilities and can replace traditional GPS units. You might have an old Garmin mount stuck to your dash and would prefer not to take it off or add another. In some cases, Garmin made some nice mounts, and you may want to leverage it.
In any case, we figured it out and offer a few excellent options for using your Garmin mount for your new device. Both solutions include a custom fitting to connect the cradle with the 17mm Nuvi ball mount.
