I would choose the specific model based on the equipment it needs to work with. GPSMAP and ECHOMAP are broad product families, and a network port is not a promise of the same capabilities across all models.
Make a wish list for your next trips
Start with the screen's purpose: charts at the helm, fishing with sonar, radar, engine information, or multiple displays. Put each wish into one of two columns: necessary now or an expected upgrade. This makes it easier to choose without paying for features you do not plan to use.
A concrete example from the range
| Point | ECHOMAP UHD2 62sv | GPSMAP 1022xsv |
|---|---|---|
| Display and operation | 6-inch touchscreen with buttons. | 10-inch display with button operation. |
| Sonar | Model and transducer are selected together; confirm desired views. | The xsv model has built-in support for traditional CHIRP, ClearVü, and SideVü with a suitable transducer. |
| Radar and network | The UHD2 6/7/9 sv manual excludes radar and GPSMAP, among other things, on its Garmin Marine Network connection. | The 10x2/12x2 series manual describes connecting a compatible Garmin radar. The specific radar must still be verified. |
The example applies to the mentioned models and their documentation. It cannot be applied to all models with GPSMAP or ECHOMAP in the name.
Compare complete solutions
Check whether the price includes a transducer and charts for your area. A base map is not the same as a detailed nautical chart. Also note any chart subscriptions, mounting brackets, network parts, and cable extensions.
If there is already Garmin equipment on the boat, include the model numbers. This also applies to an existing radar that you would like to keep. A new display should only be ordered once the planned connection has been documented.
How I would prioritize
For a project with a sonar and one compact display, I would look into the relevant ECHOMAP package. For a project with radar and multiple network functions, I would start with a GPSMAP model that supports the exact devices desired. Then, compare space, operation, and the total price.
Try the placement on paper
Measure the cutout and the space behind the dashboard, including plugs and cable bends. Feel free to make a paper template of the screen's outer dimensions. The desired screen size must also be readable from the normal steering position.
Sources and manufacturer documentation
Manufacturer documentation checked September 2026. Always follow the manual for the specific model and installation. The calculation examples are simplified examples for planning purposes.
Moving forward with your solution
Send me the names of your existing equipment and your wishes for radar and sonar, and I will help you compare specific models.
