i have a few year old edge 705, that has worked great up until a particularly wet ride on Wednesday night!
Basically, whilst it was plugged in downloading the data,it kept flashing up with "external power lost".. this stopped after a while once i had unplugged it.
then the charge screen/connected to computer screen is permanently displayed, and the device wont power on or off properly, sometimes it looks as if its going to start, but then it reverts back to one of these screens!
When i plug it into the pc, you can still open the folders etc in windows, but the unit still displays these screens!
i have tried both methods of reset, and again it looks like its going to reset, but the charge screen comes back on and stops the process!
I let the battery drain too, then re charged and its doing the same thing!
also updated software on garmin connect, this worked ok according to the pc, but the units still doing the same thing!
Anyone experienced similar, or is the unit completely fooked!?
