Hi. there.
from march of this year, i have used garmin 230 in korea. until this week, my 230 everything is fine.

but two days ago, when rainy day, i ran one hour outside. on race, pace and auto lab alarm are fine like my old races.
but after synced, i found just no map data on garmin connect. ( no map data on strava too)
( rainy day. use footpod, only gps, no heartrate, firmware 5.40)

I thought it maybe caused because of rainy day. and changed 230 setting to use gps + glonass

today, i ran half-race marathon. on race, i realized 230's distance different from race's official distance sign.
(sunny day, no use footpod, gps+glonass, no heartrate, firmware 5.40)

after race ended, there is no map data too. furthermore, my 230's distance is 23.4km (my friends garmin distance is 21.7km)

this problem is not only "no map data" but also "distance is wrong" !!!!

here is my run log : https://connect.garmin.com/modern/activity/1397116268

I think this is too serious problem, so i report my case.

------------------ after post this, i have examined 230.

after just power off / on 230, map data is shown. (don't know distance is correct)
after reset 230 ( press 15sec power button), map data is shown. (don't know distance is correct)

so, i recommend reboot garmin watch regularly for avoiding this issue.
