Shares of GPS systems and tracking-device manufacturer Garmin (GRMN - Get Report) surged on Wednesday after the company reported second-quarter earnings that surpassed analysts' forecasts, and raised its guidance for the remainder of the year on expected strong sales.

Shares of Garmin gained more than 7% after the company posted net income of $223.7 million, or $1.17 share, vs. $190.3 million, or $1 a share, in the comparable year-ago quarter. Analysts polled by FactSet had been expecting earnings of $1.01 a share. Sales jumped to $954.8 million, up from $894.5 million a year ago and well above the $929.6 million expected by analysts.

A jump in aviation-related equipment and services coupled with strong sales in its marine, fitness and outdoor segments helped offset a drop in its automotive business, where sales have declined amid the rise in popularity of apps like Google (GOOGL - Get Report) -owned Waze, which drivers incorporate into their cars using Apple's  (AAPL - Get Report) CarPlay and automakers' own software.

Garmin also produces various types of fitness and health tracking devices and software, including menstrual cycle tracking.
