I tried searching for this but didn't see anything, I have a DR500GW that wont turn on, the only light that appears is the blue GPS light, no voice prompts to let me know it has resumed normal recording or starting up and no other lights come on. tried reformatting the sd-card and also re adding the 1.008e to the sd-card, still no luck with it fully turning on. pressing reset (that turns the GPS light off until i release the button) or holding the wifi button for 10sec doesn't do anything either. Any help would be appreciated. Thanks
