I purchased a new 235 today, and when I got it out of the box it was completely dead. That seems unusual for this kind of item, but I figured it just needed to be charged.
For the first half an hour it was connected to my laptop, and the only thing that showed up on the screen was the garmin name/logo. There was no battery that shows that it's being charged. And when I went to set up garmin express it couldn't find the device. I've moved the 235 to a USB plug that goes into the socket, thinking perhaps my computer wasn't providing enough juice. However, about an hour plugged in the only thing that is showing up is the Garmin name. The buttons are not operational.
Have I just not charged the watch long enough? Am I being impatient? Or did I get a dud out of the box? I feel like this is a really stupid question but I've never encountered this sort of issue with any device of this nature before. And the quick start guide provide the impression that the 235 should come with some battery life.
