Garmin service is some of the best in the business. DH has lots of time with tech support on the auto/mc units and always speaks very highly of them. This is my first experience with them.

While I had them on the phone, I asked about a new USB port cover for the 301, which is over three years old. It's just a rubber cover and it had broken off. From my experience with other companies, I was expecting that most likely a replacement cover wouldn't be available and if it was, I'd have to pay for it since it was a discontinued unit, two years out of warranty. Garmin sent me two of those for free, too.
