Shares of Garmin (GRMN) - Get Report were popping by 6.3% to $53.15 in premarket trading on Wednesday morning, after the technology company posted better than expected second quarter earnings.

The GPS navigation and wireless device maker posted adjusted quarterly earnings of 88 cents per share, 7 cents above analysts' expectations. Revenue came in at $817 million, $9.17 million more than Wall Street had forecast.

Garmin got a boost from its fitness products, which helped to offset a not so strong vehicle navigation segment.

"We delivered another quarter of revenue and earnings growth led by strong double-digit growth in our outdoor and aviation segments," Garmin CEO Cliff Pemble said.
