I've just brought a 2008 T180, but there are no manuals. I'd like to get a manual for the Sat Nav, but I'm not sure which model it is so I can google it. The Sat Nav has got the CD and Sat Nav disc slots hidden behind the screen, which slides down when you click on the open button. I'd also like to know where the best place is to download a drivers manual, if there is one?
