PPendix

You can use an optional external remote 

antenna (Garmin GA 25MCX). To 

purchase, go to 

or 

www.garmin 

 link. 

Pull back the weather cap from the MCX 

connector located on the back of the 

zūmo, and connect the antenna. 

Your zūmo must acquire GPS (Global 

Positioning System) satellite signals 

to operate. If you are indoors, near tall 

buildings or trees, or in a parking garage, 

your zūmo cannot acquire satellites. 

Go outside to an area free from tall 

obstructions to use your zūmo. 
When your zūmo has acquired satellite 

signals, the signal strength bars on the 

Menu page are green 

. When it 

loses satellite signals, the bars turn red or 

disappear 

.
