I thought I let my Garmin go without a charge too long … No biggie, I’ve got Strava on my Android phone, and I can you that in the interim. I plug in the charger in to my iMac. Wake up the next morning, and damn, it’s still dead. It wouldn’t even beep when I plugged in the charger.
Check online, and yup, it’s out of warranty. Time to upgrade to the 520.
Looking back, I’ve only had the 510 some March 2014. That’s only 2 years. That’s not very long for a hardware device. Hope this one will last a little longer.
