President and Chief Executive Officer at Garmin
Thank you, Terry. Good morning, everyone.
As announced earlier today, Garmin reported record revenue and operating income for the second quarter. Consolidated revenue increased 53% over the prior year and exceeded $1.3 billion. We experienced strong double-digit growth in all five business segments. Profitability in the quarter was also strong. Operating margin expanded to 28%, and operating income increased 97% to $371 million.
There are two important things to consider when looking at our Q2 performance. First, Q2 of 2020 was negatively impacted by the onset of the COVID-19 pandemic, which reduced consumer demand and disrupted our retail partners. As a result, a portion of the current period growth is attributable to the unusual comparable from the prior year. Second, the compound annual growth rate from 2019 to 2021 was 18% for the period, which is very much in line with recent trends during quarters less impacted by the dynamics of the pandemic. We believe this indicates that the underlying market is healthy and continues to grow.
To meet the growing demand for our products, I'm pleased to report that later this fall, we plan to open our fourth production facility in Taiwan, which will approximately double our capacity. This is part of a multi-year initiative to improve our capacity and prepare for opportunities that lie ahead. Also, we entered a new phase of our Olathe facility expansion to convert the former warehouse building into additional office space. These projects follow the recent completion of other notable investments, including a new production facility for Tacx cycling trainers, our new auto OEM production facility in Europe, and the expansion of our Olathe facility to include auto OEM production.
Given our strong performance in the first half of the year, we are updating our full year guidance. We now anticipate revenue of approximately $4.9 billion, up 17% over the prior year, with double-digit growth expected in each of our five business segments. In a moment, Doug will provide more details on our financial results and updated guidance, but first I'll provide a few brief remarks on the performance and outlook of our business segments.
Starting with Fitness, revenue increased 40% to $413 million, with growth across all categories led by cycling products and advanced wearables. During the quarter, we celebrated Global Running Day with the launch of two new running watches, the Forerunner 55 and the Forerunner 945 LTE. The Forerunner 945 LTE is noteworthy because it includes built-in connectivity and leverages a safety monitoring capability of our recent GEOS acquisition. We also launched the Venu 2 smartwatch in two sizes, which will enhance the appeal of these devices across a broader range of customers. Given the strong performance of the Fitness segment, we're raising our revenue growth estimate to 17% for the year.
Moving to Outdoor, revenue increased 57% to $323 million, with growth across all categories, led by adventure watches. During the quarter, we launched our smallest dive watch, the Descent Mk2S, featuring multiple dive modes, multisport training and smartwatch features for everyday use. Given the strong performance of the Outdoor segment, we are raising our revenue growth estimate to 17% for the year.
Looking next at Aviation, revenue increased 43% to $181 million, and we experienced growth in both OEM and aftermarket categories. Revenue to the -- in the quarter was comparable to the levels achieved in the second quarter of 2019, which is significant considering the impact ADS-B had on 2019 performance. During the quarter, Autoland was awarded the prestigious Robert J. Collier Trophy as the year's greatest achievement in the field of aeronautics or astronautics. Autoland is the first certified autonomous system designed to activate during an emergency to safely fly and land the aircraft without human intervention.
We also announced the acquisition of AeroData, a leading provider of performance information for commercial aircraft serving more than 135 airlines worldwide. AeroData broadens our presence in commercial [Technical Issues] and we look forward to building on their success.
We're pleased with how the Aviation segment has recovered from the impact of the pandemic and the completion of the ADS-B mandate. We now expect full year revenue to increase approximately 10%.
Turning next to the Marine segment, revenue increased 66% to $262 million, with growth across multiple categories led by chartplotters. During the quarter, we announced support for Mercury's SmartCraft engines, expanding the list of engines compatible with our display systems. We also launched the MSC 10 marine satellite compass, which provides precise position and heading information without the interference challenges associated with traditional magnetic compass systems. The Marine segment is off to a great start in 2021 and we expect that demand will continue to be strong throughout the remainder of the year. With this in mind, we expect full year revenue to increase approximately 27%.
And looking, finally, at Auto, revenue increased 74% to $148 million, with growth contributions from both consumer categories and new OEM programs. During the quarter, we launched our first connected dash cam with live view monitoring and premium subscription-based cloud storage. Given the strong start to the year, we now expect the Auto segment to increase approximately 15%.
In summary, we're very pleased with our performance so far, which gives us confidence to raise our guidance for the year. In addition, we are investing for the future by expanding both our production capacity and office facilities. So we are well positioned to seize opportunities that lie ahead.
That concludes my remarks. Next, Doug will walk you through additional details on our financial results and our updated guidance. Doug?
