Sunday morning, I decided to update my Zumo 660 to the latest maps/software. It churned away all day and when I ejected it. I discovered it was now an expensive brick. No matter how I tried to boot/reset it, it would go to "LOADER LOADING" and lock up. I have to give Garmin lots of credit on how they responded. I e-mailed them Sunday night and got a response around 6:00 Monday morning. Unfortunately, the directions didn't fix it and I spent ~30 minutes on the phone with a technical rep working through it. After determining it couldn't be fixed remotely, he issued a RMA and cut the standard (out of warranty) repair price in half as he could see I was a loyal customer (4 registered GPSs in the system). I explained I was headed to the rally later this month and really needed it back quickly. He said not to worry and wasn't kidding! I dropped it off at UPS Monday afternoon and it was signed for at Garmin Tuesday morning around 10:30. Tuesday evening, I received an e-mail saying the replacement had been shipped - about 8 hours to process it. The "new" GPS should be on my doorstep tomorrow. That's some good customer service.
