I crashed once, edge hit the ground and hung/freezed, after turning off, it never turned on again... and main screen has some cracks.
Does Garmin repair stuff? what are the options now?
only the new one ?
Yes, Garmin does repair. It is usually a flat rate repair rate. You send them the old device and payment, they send you a refurbished unit. They will sometimes even cross ship with an extra, refundable, credit card charge. I've had pretty good experiences with their repair process.
