I've given them a few chances but they've failed me again and again.
Here's my opinion of Garmin. Complete pants. Do not buy their products, please buy GPS devices from another manufacturer.
I bought an HCX legend a few months ago. After about a month the device started turning itself off for no reason. I initially though it might be a loose battery but they were in nice and stiff and shaking and banging it about didn't make it turn off, only when I was moving around (i.e. riding along) would it fail. I spent a couple of weeks trying to get Garmin to help me and after a while they eventually gave me a returns number.
I got a new device back after a week or so but this started showing exactly the same problems about a week later. I asked Garmin to sort me out again saying I was very unhappy and they completely ignored me.
There is no record of the ticket I raised on their hard to use website so whether it just got lost in their system or was deliberately deleted I don't know but their customer service sucks almost as bad as their products. They don't even have a record of the original repair.
Don't buy.
