Anyone who has ever used a SatNav will know that they can be a bit temperamental. Sometimes they tell you to turn too late, or the map isn't updated properly - there's countless reasons people get annoyed with them.

Actor Paddy Murphy shared the footage on his Facebook page, and it has since garnered thousands of shares.
