GPS Repair Problems? Ask a GPS Technician for Answers ASAP
Hi and welcome to JustAnswer,Thank you for the question and your patience. Should you still need assistance for information purposes only...Initially, the only easy user doable try would be to charge it again. By design, the Garmin fēnix 2 would turn on when connected to a power source and/or a charger.
If problem persist, then it would be an internal hardware issue.
