Garmin zumo 3x0 Replacement Weather Caps (Set of 2, Black)

Riding through rain or dust, your Garmin zumo 3x0 motorcycle GPS faces the elements head-on. Over time, the small rubber caps that shield its USB and audio/power ports can wear out, crack, or go missing—leaving your device vulnerable to moisture and debris. This set of two replacement weather caps restores that critical protection, keeping your navigation reliable mile after mile.

Why choose it

These caps are not just cosmetic—they are essential for the longevity of your zumo. By sealing the ports, they prevent water ingress, dust buildup, and corrosion that can cause charging failures or audio issues. The UV-resistant material won't degrade in sunlight, and the flexible design stays put even on rough rides. Replacing worn caps is far cheaper than repairing a water-damaged GPS.

Ideal use cases

• Motorcycle touring in variable weather conditions
• Off-road or adventure riding where dust and mud are common
• Replacing lost or damaged original caps after years of use
• Keeping a spare set in your tank bag for on-the-road fixes

Good to know

Installation takes seconds: simply press each cap into its corresponding port until it sits flush. For best results, ensure the port area is clean and dry before fitting. While these caps help maintain water resistance, always check that they are fully seated before exposing the device to heavy rain or washing.
