SAT NAV rage is something most drivers have battled with at one point or another.
But for this unfortunate Irish motorist the fight became all too real as he unsuccessfully tried to navigate his way along Ireland's roads.
In the video posted on Facebook by Paddy Murphy the increasingly irate driver makes several attempts to select a new destination, to which the sav nav calmly continues to reply: "Sorry, please speak."
A passenger in the car attempts to help by telling the driver to "try again and talk very clearly" but to no avail.
With the frustration building at every second, be warned - there are some words in the following video that some people might find offensive.
