eTrex SE Bug 5: The Galileo ID numbers displayed on the Satellite page are incorrect (subtract 47 from each for correct ID).
While comparing the eTrex SE to other Garmin devices to create supporting documentation, I couldn't help but notice that models sharing unique GNSS chipsets also favored specific satellites. All screen captures below were taken at the same location within a minute of each other. For these examples, we were focusing on the Galileo constellation.
The eTrex SE and GPSMAP 67/67i both found 7 Galileo satellites with the Airoha AG3335M/N GNSS chipset:
Airoha AG3335M/N
The GPSMAP 65 and GPSMAP 66sr both found 6 Galileo satellites with the BCM47758 GNSS chipset:
BCM47758
The GPSMAP 66s/st/i and Montana 7x0 all found 3-4 Galileo satellites with the Type M5 (3313) GNSS chipset:
