The marketing agency has trained and educated store staff on the features and benefits of Navman products.
The campaign is also supported by a range of point-of-sale materials, including dummy display boxes, which will feature in stores throughout the winter period.
Daniel Todaro, managing director at Gekko Partners, said: "At this time of year, it is imperative that companies carry out field marketing. This is even more so for Navman, as the competition has been running merchandising programmes for some time.
"Through our knowledge of the retail technology environment we have successfully implemented a merchandising programme to position Navman as the number one."
Gekko has also attended several seasonal sales conferences in order to speak to the target audience to raise awareness of its products and how they work.
New Zealand-based Navman was established in 1988 and bought by Brunswick Corporation, a global marine company, in June 2004.
