A device having a documented BlueNet network path does not promise every old feature will behave exactly like a current device.

This checker answers a narrow network-reuse question: does Garmin document a path for the device to remain in a BlueNet-era system?

What the result does not promise

It does not guarantee full feature parity, every software capability, sensor/transducer support, autopilot integration or navigation behavior on a new chartplotter.

Verify the exact upgrade goal

If a specific radar mode, sonar feature, control function or data behavior matters to the purchase, verify that feature in the exact current chartplotter/device documentation in addition to network compatibility.
