Head-to-head
Garmin ECHOMAP UHD2 73cv vs STRIKER Vivid 7cv: ECHOMAP adds charts and compatible sonar sharing without more screen pixels
The short answer
Choose ECHOMAP UHD2 73cv when detailed charts or compatible two-device sonar sharing are required. Choose Vivid 7cv when a standalone sonar display with Quickdraw contours covers the trip. Both use a seven-inch 800 x 480 screen, so ECHOMAP adds chart and connection capabilities without a screen-resolution increase.

What matters in practice
The differences that matter
Buying a chart requires the compatible head unit
ECHOMAP accepts supported detailed charts. Vivid 7cv cannot receive them even through ActiveCaptain.
How we reached this conclusion
Garmin distinguishes supported chart installation from Quickdraw community contour transfers.
A second station needs a model-matched sharing plan
ECHOMAP UHD2 73cv can share sonar with one other compatible ECHOMAP. Vivid 7cv cannot fill that role.
How we reached this conclusion
The current keyed-model manual limits sharing to two compatible devices and specifies host roles.
The chart upgrade does not enlarge the sonar screen
Both publish the same seven-inch diagonal and 800 x 480 resolution.
How we reached this conclusion
Equal panel dimensions and pixel counts do not establish equal visibility or image processing.

Meaningful differences
What changes the fit
| What changes | Garmin ECHOMAP UHD2 73cv | Garmin STRIKER Vivid 7cv | Why it matters |
|---|---|---|---|
| Display | 7 inches, 800 x 480 | 7 inches, 800 x 480 | The chartplotter upgrade does not add display pixels. |
| Detailed chart support | Compatible regional charts supported | Supplemental detailed charts unsupported | Chart compatibility is separate from recording contours. |
| Memory-card slot | One microSD slot | No memory-card slot | ECHOMAP provides a physical card path for supported content. |
| Wireless sonar sharing | Two compatible ECHOMAP devices | No ECHOMAP sonar-sharing role | Check both model names and the required host role. |
| Local depth contours | Quickdraw supported | Quickdraw supported | Self-recorded contours are shared ground. |
What you give up
Every choice has a cost
If you choose Garmin ECHOMAP UHD2 73cv
- Wireless sharing requires a compatible second model and the correct host setup.
If you choose Garmin STRIKER Vivid 7cv
- It cannot become the second station in an ECHOMAP sonar-sharing pair.
Recommendation switch
The decision flips if...
I need detailed chart content on the head unit
Choose Garmin ECHOMAP UHD2 73cv. ECHOMAP supports compatible charts.
Quickdraw and standalone sonar cover my fishing
Choose Garmin STRIKER Vivid 7cv. Vivid 7cv provides that workflow.
My only goal is a larger display
Choose neither. Both publish the same screen size.
What matters in practice
How to make the call
Buying a chart requires the compatible head unit
If you need detailed regional chart content on the fish finder, select ECHOMAP and verify the coverage and license for the exact package. Vivid 7cv can record and use Quickdraw contours, but that does not unlock purchased navigation charts. The selected Amazon ECHOMAP bundle map edition must be confirmed rather than copied from another regional product page.
A second station needs a model-matched sharing plan
For a helm and bow display, verify the second ECHOMAP model before ordering either unit. When paired with UHD2 6/7/9 sv or Ultra 2, that sv or Ultra 2 must be the network host. Two compatible units can use the transducer connected to one source. Wi-Fi on Vivid 7cv should not be mistaken for this chartplotter sonar-sharing function.
The chart upgrade does not enlarge the sonar screen
If the current problem is a cramped split-screen view, changing to this ECHOMAP will not provide a larger panel. Its case rests on the chart and connectivity functions. Vivid 7cv can remain sufficient when local contours and standalone sonar cover the job. Compare a genuinely larger screen if viewing area is the unresolved constraint.
What this comparison cannot tell you
- The current Amazon page confirms ECHOMAP UHD2 73cv identity but did not resolve every bundle component. No exact included map edition or transducer is promised here. No matched sonar or display test was performed.
