Since 265 does not have LTE, the only relevant thing to SAR is its Bluetooth Low Energy connections. I haven't seen anything from Garmin, but it should be comparable to Bluetooth headsets: "While the SAR value of a cell phone is about 0.5 - 2.0 W/kg, the SAR value of a headset is only about 0.001 - 0.003 watts per kilogram (class 3 devices)."
(Wi-fi connection is probably comparable to a phone, but you don't have to use it.)
Thanks for that info! And since the SAR value in that spec is that maximum value, it's probably achieved only when you do wifi sync with the weakest possible wifi signal that still works.
