The Garmin 400, 450 and 550 button sets are prone to breaking free, we offer a service to replace missing buttons and back-fill the buttons with a special rubber urethane that helps maintain waterproofing and holds and helps prevent future button failures. We are not able to replace the whole button set as one piece but just individual buttons. You can see the process in the pictures below. For the Garmin Zumo 450 and Garmin Zumo 550 repair go to our Express Repair Service
The image on the left is starting to tear free, at this stage it may fall out of the case and will allow water to enter the watertight case. The image on the right is a button is good condition, the rubber that holds the button in place is only 1/16 of an inch so it is always a good idea to have the buttons back-filled with the silicone as a preventative repair – fix it before cracks start to let in moisture and cause unnecessary damage.
Buttons back-filled with special two-part rubber urethane. Notice the entire void around each button is completely filed and sealed – this holds the button in and prevents moisture from entering the housing.
