What this model does - and what it does not
This is an earlier generation than the UHD2 range and Garmin now files it under Previous Models. Everything below is still from Garmin's own published specification for this part number.
Included
- ✓UK and Ireland charts already loadedGarmin's own words: preloaded BlueChart mapping covering the British Isles in their entirety, including the Thames Estuary, Caledonian Canal, Outer Hebrides, Shetland and Orkney, Isle of Wight, Isle of Man, Lough Neagh, the Shannon up to Lough Kee and the Irish Sea - plus continental coverage from Brest to Kiel.
- ✓Keyed controlNo touchscreen to fight with in gloves or spray. Everything is on physical keys, which suits a small open boat and a wet hand.
- ✓CHIRP and ClearVü sonarGarmin CHIRP traditional sonar for depth and bottom type, plus CHIRP ClearVü scanning for a photograph-like view directly below. Both driven by the display itself.
- ✓NMEA 0183One receive port and NMEA 0183 compatibility, so an older DSC VHF or AIS receiver connects directly without a gateway. AIS and DSC are both supported.
- ✓Quickdraw ContoursRecords your own soundings into personalised 1 ft contour maps as you go. Garmin's line is that these are your maps and you own them - keep them private or share them.
- ✓Share with other Garmin unitsWaypoints and routes can be shared with other ECHOMAP or STRIKER units.
- ✓Bail or flush mountA tilt and swivel mount with a quick-release cradle is supplied, so the unit lifts off and stows below when the boat is left.
- ✓IPX7 and 0.7 kgWaterproof to temporary immersion, and light enough that the bail mount is genuinely practical on a small boat.
Not supported
- ✗No NMEA 2000Garmin's Networking and Connections list for this model has no NMEA 2000 row, and the 40-series connector view shows only power and transducer connections. It will not join an NMEA 2000 backbone, so it cannot read engine, tank or wind data from one.
- ✗Not an autopilot controllerGarmin states plainly that autopilot control is only available on models with NMEA 2000 network capabilities. This model has none, so it cannot steer the boat.
- ✗No radar, no Marine NetworkGarmin Marine Network ports: None. There is no way to add radar or a networked sonar module.
- ✗No video input or outputGarmin lists both as None. No camera of any kind.
- ✗No transducer suppliedGarmin's own variant name is ECHOMAP Plus 45cv without Transducer. The 4-pin sounder to 8-pin transducer adapter cable is in the box, but the transducer is not.
- ✗No Wi-Fi and no ActiveCaptainGarmin's manual states Wi-Fi is not available on ECHOMAP Plus 40 models, and ActiveCaptain is restricted to the 60, 70 and 90 series. Chart and software updates go through a card and a computer.
- ✗ClearVü only, not SideVüThis is a cv model. Garmin's sonar-type selector for this part number reads ClearVü and Traditional CHIRP - the Ultra High-Def and SideVü options are different part numbers.
- ✗An earlier generationGarmin lists this under Previous Models and its last software release was September 2021. It is still supplied and supported, but the UHD2 range is where development has moved.
What you get
Charts in the box
BlueChart cartography for the British Isles in their entirety plus the coast from Brest to Kiel, already on the unit. Nothing else to buy before the first trip.
Keys, not glass
Physical keys throughout. It works with cold wet hands and it does not need looking at to operate.
CHIRP and ClearVü
Traditional CHIRP for depth and bottom type, ClearVü for a photograph-like view of what is directly beneath the boat.
Small enough to go anywhere
4.3 inches and 0.7 kg on a quick-release cradle. It fits a tender, a RIB or a crowded small-boat console, and lifts off when you leave.
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 Plus 45cv with BlueChart for UK, Ireland and Northwest mainland Europe coast
- Power/data cable
- 4-pin sounder to 8-pin transducer adapter cable
- Tilt/swivel mount with quick release cradle
- Documentation
No transducer is included - the adapter cable is there so that an 8-pin Garmin transducer will reach the 4-pin sounder port.

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.
