Mounting Considerations
NOTICE
This device should be mounted in a location that is not exposed to extreme temperatures or conditions. The
temperature range for this device is listed in the product specifications (Specifications, page 17). Extended
exposure to temperatures exceeding the specified temperature range, in storage or operating conditions, may
cause device failure. Extreme-temperature-induced damage and related consequences are not covered by the

You can flush mount the device in the dashboard, or bail mount the device on the dashboard.
When selecting a mounting location, observe these considerations.
• You should mount the device to provide an optimal viewing angle as you operate your boat.
• You must select a location that is strong enough to support the weight of the device and protect it from
excessive vibration or shock.
• To avoid interference with a magnetic compass, you must not mount the device closer to a compass than the
compass-safe distance listed in the specifications (Specifications, page 17).
• You must select a location that allows room for the routing and connection of all cables.
• You should select a location that allows for easy access to the device touchscreen.
• You should select a location that allows for access to the microSD
®
card in the back of the device. If the
location does not allow access, you must insert the memory cards before installing the device.
