A comedian has created a downloadable satnav voiceover that directs drivers and makes jokes – in a CORNISH accent. The new app created by funnyman Colin Leggo gives users a choice of four members of the fictional Trebilcock family. The four characters – Frank, his wife Pam, son Leonard and daughter Lucy – give instructions such as “at the end of this lovely road turn right” and “exit left my darling”. Users can listen to one at a time or use the ‘world-first’ family mode setting, where the four argue with one another like real-life relatives bickering over directions. ‘Travel with the Trebilcocks’ was produced by Colin Leggo and pal Simon Truen, a cult Cornish twitter personality known as Jam First. Satnav users can download each voice onto their TomTom or Garmin device for #2.99, while the whole family can be purchased for £9.99. Joker Colin has previous created a string of viral web videos including Grand Theft Cornwall – a spoof of violent video game GTA5 where the hero rejects killing and instead searches for pasties.
