Within a week of getting my Allure 1.6 eHDI 92 with Sat Nav, I ordered a new version of TomTom because QVC had an offer including lifetime maps update.
I do still use the 208 Sat Nav but it isn't as easy to set the destination, and it doesn't do postcodes. Also the Lady gets very upset if you disobey her and seems unable to adapt to the road that you insist on following; my TomTom gives in to my wishes much more easily.
Someone on here suggested that the Peugeot Sat Nav would be updated with postcodes, but I don't know how to get updates or how to install them
