THE QUICK TAKE
Is it right for you?
This is a useful route if your Garmin swivel base matches the adapter and you want a removable, adjustable mount. The original display bracket stays attached when you lift the assembly out of the StarPort.
Do not treat it as a universal Garmin mount. Garmin uses different bases across its ranges. Check the model against RAILBLAZA’s selection guide and compare the actual base before buying.
01 / BUYING NOTES
Before you buy.
Check the round base pattern.
The adapter fastens directly to the compatible Garmin swivel base. Use the exact model selection guide, not screen size or brand alone.
Keep room to tilt.
Position the mount so the display can tilt without hitting the side of the boat. Leave a relaxed cable loop rather than pulling the lead tight.
Choose the correct StarPort base.
A StarPort rail, track or deck base completes the installation. The socket determines where the mount can attach. It is not included.

02 / AMAZON REVIEWS
The buyers’ view.
Buyers describe awkward fit with bases they identify as Garmin Vivid Striker 4 Plus, Striker 4 and Vivid 4cv. The Striker 4 owner needed another mount combined with this one to complete installation; the Vivid 4cv owner felt the result looked improvised rather than purpose-built.

RAILBLAZA’s detailed compatibility section names selected ECHOMAP and STRIKER swivel-base models and includes attachment screws and nuts. Its broader introductory text is inconsistent, so the exact base pattern and selection guide matter.
The selected 02-4178-11 package supplies the Garmin-specific adjustable mount and attachment hardware. A fish finder, swivel bracket and StarPort boat socket are not included.
