After reading several reviews I was skeptical about this GPS mount working with my Garmin Smartdrive 5, but to my surprise it fits and works perfectly. The attachment to the ball mount is very firm..not loose like some described. Some had also said when inserted into the CD drive they found it to be shaking while driving.again this was not the case for me. I drive a 2016 Nissan Frontier and it works flawlessly with no shaking at all. In the box were some 3m tape tabs to place on the unit to provide a tighter fit if the CD slot was a little to big, but I did not need them. I inserted the mounttightened it downplaced the Garmin on the mount and everything was solid. I am very pleased with this purchase, and recommend it highly. There are a few others on Amazon for a few dollars more, and had actually placed one in my cart should this one not work. I deleted it of course, and glad I did not have to send this one back.
