The ClicgearR GPS Holder installs easily and can be used to hold iphones, smart phones or GPS devices. The ClicgearR GPS Holder is designed to install in the standard umbrella mount on your Clicgear cart and securely hold your GPS unit while on the course. Designed with the mount offset to the left side, it can still be used with your standard Clicgear Umbrella holder or the Clicgear Umbrella Angle Adjuster accessories. The GPS Holder comes with two complete sets of installation hardware for two separate devices. The two rubber bumpers are reversible to adjust to fit different devices. Fits all ClicgearR and RovicR Brand Carts with a standard umbrella mount installed. *We recommend using a hard case for your iphone or smart phone to attach the installation clips to prevent damaging the device.
