I updated my sat nav because my old Mio gave up the ghoost, I got a TT 1005 which for the most part is wy ahead of my old Mio (8yrs old) . But one thng the Mio was way better at was unlimited number of way points . TT only allows 3 , this is pretty rubbish if you are tryng to organize a long route with several stops along the way.
