First you need to have the relivent map on your SD card. Typicly this will be the Tomtom Map " Western Europe ". When you purchase maps from TomTom you also get an activation code and instructions telling you how to install the map onto your device and how to authorise it using the code that comes with it.
Before doing anything ... BACK-UP your existing data ( the whole SD card ) onto your computer . This will ensure that if any update is unsuccesful you can at least return things to the way they were before you tried to update.
There are several ways to obtain maps
- buy a new TOMTOM SD card for your tomtom that containes the required maps. Make sure it comes with the authorisation card.
- buy a CD from TomTom or a TomTom authorised dealer . This CD will contain the required map so you can download the required map to your own SD card. Make sure it comes with the authorisation code AND instructions.
- buy the required map from TomTom online . You can download it to your PC , then copy it onto your SD card later. It will come with some instructions and authorisation code ...... You can also use "TomTom Home" software and this does most of the job of downloading maps ( that you buy from tomtom ) and puts them onto your sd card for you in a semi-automatic way . If you go down this route then its best to be sure you have the latest version of TomTom home software by going to the TomTom website first.
With ANY of the above methods------- BACK UP your existing SD card first . In fact ... make a BACK UP NOW , then if anything goes wrong at any time , you can at least revert back to your backup.
