The catch
Garmin ECHOMAP UHD2 73cv
The exact package determines chart coverage and software access.
Side by side
Garmin ECHOMAP UHD2 73cv vs STRIKER Vivid 7cv Compared: ECHOMAP brings charts and compatible sonar sharing, with no gain in screen pixels
Quick verdict
If you require detailed charts or compatible two-device sonar sharing, ECHOMAP UHD2 73cv is the one. If a standalone sonar display with Quickdraw contours covers your trip, Vivid 7cv will do. Each has a seven-inch 800 x 480 screen, so ECHOMAP brings chart and connection capabilities without any increase in screen resolution.
Before you buy
Why, and what it costs you
A chart purchase needs a compatible head unit
Supported detailed charts work on ECHOMAP. Vivid 7cv cannot receive them, even through ActiveCaptain.
Where this comes from
Garmin treats supported chart installation and Quickdraw community contour transfers as separate things.
The catch
Garmin STRIKER Vivid 7cv
You cannot install detailed charts you have purchased.

In practice
Differences you will notice
A chart purchase needs a compatible head unit
Supported detailed charts work on ECHOMAP. Vivid 7cv cannot receive them, even through ActiveCaptain.
How we worked this out
Garmin treats supported chart installation and Quickdraw community contour transfers as separate things.
A second station needs sharing that fits the models
ECHOMAP UHD2 73cv can share sonar with one other compatible ECHOMAP, a role Vivid 7cv cannot fill.
How we worked this out
Sharing is limited to two compatible devices in the current keyed-model manual, which also specifies host roles.
Moving to charts will not enlarge the sonar screen
The seven-inch diagonal and the 800 x 480 resolution match on both.
How we worked this out
Panels of equal dimensions and pixel counts are no proof of equal visibility or image processing.

Spec by spec
Where they really differ
| Spec | Garmin ECHOMAP UHD2 73cv | Garmin STRIKER Vivid 7cv | In practice |
|---|---|---|---|
| Display | 7 inches, 800 x 480 | 7 inches, 800 x 480 | Upgrading to the chartplotter adds no display pixels. |
| Detailed chart support | Compatible regional charts supported | Supplemental detailed charts unsupported | Recording contours is a separate matter from chart compatibility. |
| Memory-card slot | One microSD slot | No memory-card slot | Supported content reaches ECHOMAP through a physical card. |
| Wireless sonar sharing | Two compatible ECHOMAP devices | No ECHOMAP sonar-sharing role | Look at both model names and the host role that is required. |
| Local depth contours | Quickdraw supported | Quickdraw supported | Both support self-recorded contours. |
Trade-offs
What each pick costs you
With Garmin ECHOMAP UHD2 73cv
- For wireless sharing you need a compatible second model plus the correct host setup.
With Garmin STRIKER Vivid 7cv
- It cannot serve as the second station in an ECHOMAP sonar-sharing pair.
Change of plan
When the answer changes
I need detailed charts available on the head unit
Go with Garmin ECHOMAP UHD2 73cv. Compatible charts work with ECHOMAP.
My fishing is covered by Quickdraw and standalone sonar
Go with Garmin STRIKER Vivid 7cv. That workflow comes with Vivid 7cv.
All I want is a larger display
Neither model fits. Both list an identical screen size.
Decision guide
How to decide
ECHOMAP UHD2 73cv fits when detailed charts or compatible two-device sonar sharing are a requirement. Vivid 7cv fits when a standalone sonar display with Quickdraw contours is enough for the trip. The seven-inch 800 x 480 screen is the same on both, so ECHOMAP adds chart and connection capability with no gain in screen resolution.
A chart purchase needs a compatible head unit
Pick ECHOMAP if you need detailed regional chart content on the fish finder, and verify the coverage and license for the exact package. Vivid 7cv can record and use Quickdraw contours, yet that does not unlock purchased navigation charts. Confirm the map edition in the selected Amazon ECHOMAP bundle instead of copying it from another regional product page.
A second station needs sharing that fits the models
With a helm display and a bow display, verify the second ECHOMAP model before you order either unit. Paired with UHD2 6/7/9 sv or Ultra 2, the sv or Ultra 2 has to be the network host. Two compatible units can use the transducer connected to a single source. Do not mistake the Wi-Fi on Vivid 7cv for this chartplotter sonar-sharing function.
Moving to charts will not enlarge the sonar screen
A cramped split-screen view will not get a larger panel by changing to this ECHOMAP, whose case rests on its chart and connectivity functions. Vivid 7cv can stay sufficient when local contours and standalone sonar cover the job. If viewing area is the problem still unsolved, compare a genuinely larger screen.
What this page can’t tell you
- The current Amazon page confirms what the ECHOMAP UHD2 73cv is but did not settle every bundle component. This page promises no exact included map edition or transducer. No matched sonar or display test was performed.
