This GPS is used but it is professionally tested and guaranteed to be free of defects and fully functional, optional additional warranty is also available by Square Trade. As you can see in photos the Holding Mount is modified with a Garmin Ball Head Holder. The original Holder was too bulky and not as stable as the one permanently glued on the back. This Mount has advantages and disadvantages. The Advantages are that you have better stability, better suction, better grip, larger degree of motion so the device faces you better, better suction release with a release clip, and the GPS unit will not vibrate when driving a bumpy road. The Disadvantage is that the plastic adhesive looks ugly on the back, and the attachment is not removable unless you use a Hair Dryer to warm up the plastic glue.
