The APAMPS22MM fits the socket on the back of your GPS.  Use these to attach to your dash or any VSM Mount that uses the 4-hole AMPS mounting pattern.

Note:  These only fit GPS devices that utilize the 22mm ball size.  Only the items listed in the title will fit this mount.  The majority of Garmin GPS devices use the smaller 17mm ball size.  We have that size too, just contact us for details.
