A dedicated motorcycle GPS system will come equipped with a specially designed clamp and cradle that was made specifically for the purpose of attaching the device to your dashboard. If you’re using a proper GPS device like something from a brand like Garmin, there will be specific mounts that you can buy to make the process as easy as possible. If you’re just using your phone for navigation, you can simply buy any motorcycle phone mount like those listed above, and attach it in the right place. Trying to mount a GPS device with an incompatible phone holder isn’t recommended at all.
