AMSTERDAM—Dutch navigation company TomTom is searching for global PR support to help halt declining sales of satnav devices.

The company is currently in talks with a number of PR agencies regarding a lead global PR brief to support its 2014 campaigns. According to a TomTom spokesperson, the assignment will complement its existing agency network in various markets.

The sat-nav category has suffered in recent years because of similar products on smartphones, along with fewer replacement purchases. Although that decline slowed in 2013, market leader TomTom still saw sales fall in the third quarter of last year.

The company is hoping that new products such as sports watches will help revive its fortunes. TomTom's business solutions division has also performed well, providing a range of services and products in the automotive market.

TomTom also renewed its marketing focus last year, launching a new comedy campaign that aims to grow the category.
