I have just purchased a Berlingo XTR model 2011. I cannot find the access to the Multi function on-board trip computer The brochure says beneath the steering wheel?? I have tried the menu button, the mode button and the only display I get is time and temperature and date. The menu allows me to select either mpg or kpl but I cannot display the result let alone scroll through the options . Am I missing something obvious or am I looking for something that does not exist.
