DS3 crossback sat nav update

[DS3XBCk]

Hi,
I own a DS3 crossback 69plate and the sat nav needs updating. The DS garage quoted me £144 to update it!!
Is it easy to do myself?
Thanks

Well of course they will charge you to do this if you really want to pay a technician to load a USB and sit in your car for 40 minutes drinking coffee.

Use the DS App. It will tell you if the firmware or maps need updating.
