I had a TomTom GO 720 with a Western_Europe map.

In September when I have looked for a Western_Europe map, I have not found it, so I have downloaded and installed a Europe_South map with success.

Today I have looked and find that a Western_Europe map is now present here but its size is bigger than the 2Gb that we have inside a TomTom GO 720. So I have decided to buy a SD card 4Gb to put in it a Europe map.

Can you explain how to use manage the TomTom GO 720 with a map inside the SD card ?

When I will succeed to do it, I will want to know how to have also another map inside the TomTom or in the SD card. Should these new maps must have the same value 875.3613 ?

Thanks for your help. Best regards.
