What this model does - and what it does not
Everything below is from Garmin's own published specification for this part number. The right-hand column is the part most listings leave out, and on this model it is the part that decides whether it suits your boat at all.
Included
- ✓12 inch WXGA IPS touchscreen1280 x 800 on an IPS panel, with keyed assist so it stays usable in gloves and spray. The largest screen in the ECHOMAP range.
- ✓All three sonars built inGarmin CHIRP traditional sonar, ClearVü and SideVü are all listed as built in, at 600 W. ClearVü and SideVü both run the full 260/455/800/1000/1200 kHz set.
- ✓Panoptix and LiveScope readyGarmin lists support for the full LiveScope range - LiveScope 2 HD, LiveScope XR, LiveScope Plus - plus Panoptix transducers, the GLS 10 module and the GCV 20 black box.
- ✓Multi-band, multi-constellation GNSSA 10 Hz receiver working GPS, GLONASS, Galileo and BeiDou, with WAAS and multi-band support.
- ✓Autopilot control over NMEA 2000Garmin lists compatibility with the Reactor 40 autopilot family - hydraulic, mechanical, solenoid, steer-by-wire and kicker versions.
- ✓NMEA 2000One port, drawing a single LEN from the backbone, for heading sensors, autopilots, engine data, AIS, DSC and Fusion-Link audio.
- ✓Two microSD slotsTwo card slots taking up to 1 TB, so charts and Quickdraw data can live on separate cards.
- ✓Sailing featuresGarmin lists sailing features on this model's specification, alongside ActiveCaptain mobile planning and Garmin Quickdraw Contours.
Not supported
- ✗No radar, and no way to add itGarmin's installation manual is explicit: this device is not compatible with the Garmin BlueNet network or the Garmin Marine Network, and you should not connect devices such as a GPSMAP chartplotter or a Garmin radar. If radar is on your list, now or later, you need a GPSMAP.
- ✗The network port only reaches sonarGarmin describes the NETWORK port as a connection for compatible Panoptix, GCV and ECHOMAP devices. It is a sonar and second-screen network, not a full marine network - it will not carry radar and will not talk to a GPSMAP.
- ✗Garmin states no preloaded cartographyUnlike the ECHOMAP UHD2 UK models, Garmin's page for this part number makes no claim about charts on the unit. Garmin Navionics+ and Vision+ are listed under Optional map support, and the overview calls the cartography optional. Budget for a chart card.
- ✗No NMEA 0183There is no 0183 port on the unit and none in Garmin's connector view. The power cable's brown and blue conductors are, in Garmin's words, not used by this device. An older DSC VHF, AIS or instrument system needs an NMEA 2000 gateway.
- ✗No video inputGarmin's connector view lists every port on the unit and there is no video input of any kind.
- ✗9 to 18 Vdc onlyA 24 V boat needs a converter. The GPSMAP range accepts 10 to 32 Vdc natively.
- ✗No transducer suppliedGarmin's variant name is 122sv without Transducer. The sonar is in the display, but the 12-pin scanning sonar port has nothing plugged into it until you add one.
- ✗Ultra High-Definition comes from the transducerGarmin attributes UHD scanning to the bundled GT56 transducer, not to the display. Since this part number ships without one, the UHD claim is not deliverable out of the box.
What you get
Twelve inches of IPS
1280 x 800 with keyed assist alongside the touchscreen. Room to run a chart and a sounder side by side without either being useless.
Three sonars, 600 watts
CHIRP traditional, ClearVü and SideVü all built into the display, with ClearVü and SideVü running the full 260 to 1200 kHz frequency set.
Multi-band GNSS at 10 Hz
GPS, GLONASS, Galileo and BeiDou with WAAS and multi-band reception, updating ten times a second.
Live sonar ready
The full LiveScope range, Panoptix transducers, the GLS 10 module and the GCV 20 black box all connect over the network port.
Reading a Garmin model number
Garmin naming looks impenetrable until someone shows you the pattern. Once you can read it, the whole range makes sense in about ten seconds.
12 inch screen
Garmin's own model names run 102sv, 122sv and 162sv for the 10, 12 and 16 inch displays, so the leading digits track the nominal screen size.
Ultra 2 series
The shared 2 corresponds to the Ultra 2 generation. Garmin's own manual covers the range as the 100/120/160 Series.
ClearVü and SideVü
Every sv model in this range lists both ClearVü and SideVü as built in. Garmin does not state anywhere that the letters stand for those views.
Garmin publishes no decoding key for the ECHOMAP naming scheme. The mapping above is read off Garmin's own model names across their three product pages, so it holds for this range rather than being a rule you can extrapolate. Note also that Garmin does not append a cartography code to the Ultra 2 variant names at all - the variant is simply 122sv without Transducer.
Which of these sonars will you actually use?
We sell to more cruising sailors than anglers, so here is the honest version rather than the tournament-fishing version.
Traditional CHIRP
Sweeps a range of frequencies in one transmission rather than pinging a single note, which separates targets far more cleanly. This is your depth sounder - water under the keel, and a read on whether the bottom is sand, weed or rock.
Garmin ClearVü
Down-scanning. A thin fore-and-aft slice directly under the hull, rendered almost photographically. Good for picking out a wreck, a mooring block or the edge of a weed bed as you pass over it.
Garmin SideVü
Images a swath of seabed out to port and starboard. Needs slow, straight, steady running to give a clean picture. Genuinely handy hunting for a lost mooring chain; less so on passage.
Ultra High-Definition
Not a fourth sonar - it is ClearVü and SideVü run at higher frequencies. The usual trade applies: more detail, less depth. Designed around shallow, clear inshore water.

Fitting it
- Tilt mount with quick-release cradle supplied - drill four 3 mm pilot holes
- Flush mounting is supported, but the kit and template are a separate purchase
- Swivel base is not available for the 9 inch model
- Allow clearance behind the panel for the cradle and connector bundle
- Cut from the template supplied with the flush kit, not from the device dimensions
NMEA 2000 basics
- Linear backbone with T-connectors, one drop cable per device
- A 120 ohm terminator at each end - the most common DIY mistake
- Drop cables 6 m maximum; backbone 100 m maximum
- Power the network from the ignition or a switch, never straight off the battery
- 1 LEN = 50 mA, so a chartplotter at LEN 1 barely loads the bus
The three questions we get asked every time
Three questions come up on the phone almost every week. Here is what we tell our customers.
Why is it sold without a transducer?
Because the UK models we stock are display-only - and because for most of our customers that is the right answer anyway.
- The bundled transducer on overseas versions is nearly always a transom mount, which lifts clear of the water the moment a yacht heels
- Many boats already have depth on the NMEA 2000 bus from existing instruments - the plotter simply reads it
- An existing Garmin transducer can often be reused with an adapter cable
- Buying the display bare and pairing it with a through-hull is a better install, not a compromise
Which transducer, and where does it go?
Three fittings, and the right one depends far more on your hull than on the display in front of it.
- Transom mount - the simplest to fit, no hole in the hull, adjustable afterwards. Unsuitable for a yacht that heels; vulnerable on a drying mooring
- Through-hull - best signal and best at speed, the standard answer for a keelboat. Needs a haul-out, and usually a fairing block on a deep-V or sailing hull
- In-hull - no hull penetration, fits afloat, nothing to snag. Only works through solid GRP, never through a cored laminate, steel or aluminium, and you lose some sensitivity
Which models come with UK charts?
This is the question that catches people out, because the two Garmin ranges answer it differently.
- ECHOMAP UHD2 - Garmin Navionics+ for UK and Ireland is already loaded, with a year of daily updates. Nothing else to buy before your first trip
- GPSMAP - a worldwide basemap only. That is a coarse global outline, so a Garmin Navionics+ or BlueChart g3 card is needed as well as the display
- Vision+ is the optional step up on either range: it adds relief shading, satellite and aerial harbour imagery and 3D views
- Charts keep working when a subscription lapses - you stop receiving updates, you do not lose the cartography
What arrives, and what you will still need
Supplied
- ECHOMAP Ultra 122sv

Not sure which Garmin fits your boat?
Radar or no radar, 12 V or 24 V, transom or through-hull - a two-minute conversation usually saves a return. We have been fitting marine electronics at Fox's Marina since 1927.
