Overview

The Garmin ECHOMAP UHD2 sv is a chartplotter and fishfinder combo that puts mapping and sonar on one keyed touchscreen for everyday navigation and finding structure. It is available in 6 inch, 7 inch, and 9 inch display sizes, with 800 x 480 resolution on the 6 and 7 inch models and 1024 x 600 on the 9 inch model.

Power is 9 to 18 Vdc and a fast-acting 3 A fuse is included for circuit protection. The housing carries an IPX7 water rating, which suits an open helm where spray and washdowns are part of normal use.

For fishfinding, sv models support traditional CHIRP plus ClearVü and SideVü scanning sonar when paired with a compatible transducer, with 500 W RMS sonar output. LiveScope and Perspective sonar views are supported when a LiveScope system is connected. Built-in Wi-Fi handles the ActiveCaptain connection and also supports wireless sharing between compatible ECHOMAP UHD2 units.

Key features

• Keyed touchscreen interface with Keyed Assist for fast zoom and waypoint work when the boat is moving
• Display size options: 6 inch and 7 inch (800 x 480), or 9 inch (1024 x 600)
• Preloaded Garmin Navionics+ mapping options that vary by configuration: U.S. Inland or U.S. Coastal
• Traditional CHIRP plus ClearVü and SideVü scanning sonar support with a compatible transducer; 500 W RMS output
• LiveScope and Perspective sonar views supported when a LiveScope system is connected
• Built-in Wi-Fi for ActiveCaptain pairing, software updates, and wireless sharing between compatible units
• 9 to 18 Vdc power input, fast-acting 3 A fuse included, and IPX7 water rating for typical helm exposure

Variants

Configurations vary by display size (6 inch, 7 inch, or 9 inch), the included Garmin Navionics+ mapping region (Inland or Coastal), and whether a transducer is included.

Transducer-included bundles streamline the first install on a boat that is starting from scratch. No-transducer configurations leave room to reuse an existing compatible transducer or to match the transducer choice to the way you fish and the mounting location.

Installation and setup

Choose a mounting spot where the screen stays easy to read from the helm and the controls are within reach. Plan for cable routing and connector space behind the unit; the recommended clearance to the nearest obstruction behind the chartplotter is 118 mm (4 5/8 in.). Wire to a steady DC source within the 9 to 18 Vdc range, keep the 3 A fuse in-line, and avoid long runs on undersized wire that can cause voltage drop.

For sonar, connect a compatible transducer and select the correct transducer profile during setup so the unit can display the right sonar views. When a LiveScope system is added, LiveScope and Perspective pages become available in the sonar views for real-time target and structure tracking.

Networking and system integration

If your boat has an NMEA 2000 backbone, the cradle includes an NMEA 2000 connection point to tie the chartplotter into a standard network for compatible data sharing and display. Built-in Wi-Fi supports the ActiveCaptain connection and can link compatible ECHOMAP UHD2 units for sharing user data and sonar sources while connected.

Who it fits on board

This is a good match for anglers who want SideVü and ClearVü views on the same screen as charts, and for boats where one display needs to cover both navigation and fishfinding. The main fit decisions are helm screen size, whether Inland or Coastal chart coverage makes sense for your water, and whether you want a transducer included.
