No. Nikon cameras with Bluetooth generally do not act as a Bluetooth master that can pair with and receive GPS data directly from a Garmin GPS receiver. On these cameras, Bluetooth is primarily intended for Nikon’s SnapBridge connection with a smartphone or tablet, not for generic GPS data transfer from third-party Bluetooth devices.

So even if both the Garmin and the Nikon have Bluetooth, that does not mean they can exchange location data directly. A common alternative is geotagging later by matching the camera’s photo timestamps to a GPS track log, though that is more manual.
