Hi thereI use Loco GW52 (besides two of mine GT31)Allways in Aquapack, device never been fallen, broken or any kind of damage. I don't use is so far 4 months becouse of ice and winter but now, display is kind of unreadable. What can be wrong, no water in devise or moisture, I've tried to re-firmware it, no help, GW52 is correctly connect to software, all data is there and settings is ok, also it write log just you cant read nothing from screen
