Garmin is no longer just about GPS navigation in cars. It isn't even about golf watches. An almost unlikely player in the wearable market, Garmin has started making smartwatches and fitness wearables to jump on that still unstable industry. Despite the uncertainty and the number of players already in the market, Garmin is showing no hints of slowing down. In fact, it might have as many as six such wearable devices coming next week, and four of them have already been leaked.
