Constant Aviation announced all locations in its nationwide network are now Garmin-authorized dealers. “Our relationship with Garmin has been a long-term partnership. As our network of locations grows, it is important to us to be able to provide the same services to our customers at any location. We have seen an increased number of requests for avionics upgrades from our customers, and this dealership is necessary to offer them the right solution for their needs,” said Stephen Maiden, president and CEO. The company has facilities in Cleveland, Birmingham and Las Vegas.
