Hmm not very happy with my new Garmin from Wiggle:
Have had a problem with a very small chip occurring at the edge of the screen - it has not been dropped or in an accident and is similar to the guys here on the Garmin forums above.
Email Wiggle with the images on request and they said:
Thank you for your email.
I have checked with our returns department and unfortunately this problem will not come under the Garmin warranty as they do not cover screens that have been chipped.
Apologies for the inconvenience.
