GPS signal suddenly not working:(

will try it . if that doesnt work. might go down the replace route 

Ok. I have to tell you that if you have any apps installed, they will all be deleted. In fact, it could be an app that may be causing that GPS issue. Anyway, good luck.

thanks didnt work sent watch in and paid for replacement 

I have the same problem!

Same thing here. Out of warranty, but no longer a GPS signal... no clue what could be the issue.

Same to my 735xt with version 9.80 3.30 gps. Anyone find a solution to this?

Make sure you sync with Garmin connect. I usually put my watch outside on the porch and select the activity while I warm up. Sometimes it takes a few minutes but it always acquires a signal eventually

Good advice, and always. what I do anyway.  But what happens to me occasionally since the recent updates is that maybe 4 miles into a run when the GPS has been perfect (I can see that on the map afterwards) and I'm in wide-open countryside, the GPS just drifts off for no obvious reason for maybe a mile and then sorts itself out again and is perfect for the remaining miles.  Drifts down in the recorded pace profile followed by sudden jumps up to a high speed despite no real change in my real pace are a giveaway too.  Also in the middle of a run where it takes a detour through the local reservoir....

Did not have any issues with the watch a week ago. Synced with Garmin connect and garmin express but I have the same probem
