TomTom has blamed a “leap year bug” for a fault which has caused some of its satellite navigation devices to stop working.
The firm said that a problem with its global positioning system firmware was causing “a limited number of models” to fail to identify their location.
Affected users are presented with a grey screen and a message saying the machine lacks a GPS signal.
The firm said that it was working on a fix and promised further updates.
The Dutch company said that the issue first emerged on 31 March.
It suggested that customers should reset their devices, saying the move acted as a temporary fix.
TomTom told the BBC that it would “update customers on which models are affected as soon as we know more”.
