A Garmin GPS does more with the right accessories, and this collection covers the batteries, mounts, external antennas, memory cards, and charging gear that round out a handheld or portable Garmin device. The most important thing is matching each accessory to your exact Garmin model, since batteries, mounts, and cables are model specific and will not cross over between devices.

Power: batteries and charging

A spare battery keeps a handheld going through a long day, and a charged backup is cheap insurance on the water or the trail. Garmin offers rechargeable lithium-ion packs for devices like the Delta and other units, plus chargers and 12-volt cables. Match the battery pack and charger to your device, and keep a charged spare so a dead unit is a quick swap.

Mounts for the helm, dash, or rail

The right mount puts the GPS where you can see and reach it. Garmin offers bracket, suction, rail, and flush mounts depending on the device, so match the mount to your unit and where you want it. A solid mount keeps the device steady and readable while you run.

External antennas

An external GA antenna improves reception when the device sits under a hardtop, in a cabin, or anywhere the internal antenna struggles. If your GPS loses signal in covered spots, an external antenna and the right cable restore a solid lock. Match the antenna and connector to your device.

Memory cards and data

Many Garmin units use SD or microSD cards for maps, charts, and saved data. Use a card that meets the device spec for capacity and speed, and keep maps and waypoints backed up. The right card lets you load detailed maps and store more tracks and routes.

Match everything to your model

Garmin accessories are tied to specific device families, so a battery, mount, or antenna for one model will not fit another. Identify your Garmin model number before ordering so every accessory fits and works as intended.
