I have given my husband my 6 month old Fr245 as I have another smaller sports watch to use. However, although I have removed the 245 from my account, I cannot pair it to his iphone. I don't know what to try next! I've gone through the Garmin troubleshooting list but nothing helps. Garmin Connect is on his iphone and he has an account but it is unable to find the Fr245. I don't know what else to try.
