So, not the usual kind of device I post about but while looking for Edge 820 evidence this morning I found this on the FCC website which is clearly a GPSMap 66s (It’s orange, so must be the s variant). I’ve no idea what they may have changed – it still looks identical to the GPSMap 62s and the only difference on the 64s was the inclusion of Bluetooth for uploads. Perhaps a new screen or better processor, which itself could improve battery life. Maybe a PLB type function to signal distress as these have been approved for mountain use relatively recently. Well, more recently than the GPSMap 64 release.
