Well the GPS died just before my camping trip. What a hassle. The night before that it worked just fine, then in the morning it refuses to turn on anymore. Thank god my friend has one in his car so we weren't totally lost!
After checking around, it turns out that there is a firmware issue with the Garmin 7x5T series. So they are actually giving free shipping and replacement -

However, if you're lucky enough that you can still power on your unit, updating the firmware with the latest one will fix the issue -
