Hi, I just got a new GT31 a few weeks back and used it for the first time this weekend. I charged it for the first time on Friday night and updated it to the latest firmware on Saturday. Then yesterday I used it all morning and speeds were coming up on the screen as expected. I powered it down to and then realised I forgot my card reader so tried to power it up again to use the NaviLink and a USB cable to download the data however it wouldn't turn on again!! It was completely sealed and was dry when I took it out of the aquapak so it is not water/moisture related. It wasn't banged off anything either.
I tried plugging it into a car charger to see if the issue was related to the battery however it will still not turn on. I've tried pressing the power button repeatedly and for longer periods of time but nothing comes up on the screen. Even when I plug it into power I don't get the normal battery logo and the led does not flash either.
Its very frustrating as I was competing in a competition yesterday and because I couldn't get the data off I cannot get a result. Unfortunately I didn't have a memory card in it at the time otherwise i could have got the results from that.
Has anyone had this issue before or do you know of anything else I can try to see if I can get it to work again?
I appreciate your help
