My TomTom Golfer 2 watch worked perfectly for about 18 months until the screen display became distorted and fuzzy enough to become illegible. I discovered that the cable connector was faulty and one of the 4 pins was not connecting properly. I tried to repair the pin, and reset the watch but it disconnected in the process. I ordered a new cable, and watch seemed to charge ok. However when disconnecting the display shows the time & seems normal for about an hour, then the screen locks with the PC/watch symbol. I followed TomTom instructions, but cannot reset as the syncing/update stops in mid-process ("installing watch update" stuck at 5%) for several hours (10-12+). Basically the watch will not update, to allow a factory reset, and is unusable.
Does anyone know what to do now?
