There is a book by Ann Handley and C.C. Chapman that Garmin should read regarding the state of competition online. It outlines the fact that even huge companies like Garmin will loose customers if they don't have proper content and listen to thier customer needs.
"A new online start-up, even a one-person operation, can compete with the largest multinational corporations – if it offers superior online content, including blogs, videos, podcasts, webinars, ebooks and web links. Develop great content and your company will be the one that engages people online, even ahead of competitors many times your size. Internet experts Ann Handley and C.C. Chapman use helpful rules and detailed case studies to teach you how to plan, create, and publish online content that will excite your prospects and make them want to buy from you." by Ann Handley and C.C.
