my Garmin rally rs100 is not doubling the power with garmin edge 1040. Is there any option tab in garmin edge 1040 which allows me to double single sided power. I have made sure it's connected thru ant+, I have calibrated it, removed and again connected. Still nothing. It's giving half the power. An Rs100 was supposed to double the left sided power, that was mentioned on the manual. And yes i have checked my power with a dual sided rs200 power meter too. My rs100 is just not doubling the single sided power like its supposed to.
