Basic question on updating maps on 2011 Peugeot

Hi all
I have read through all these relevant posts a few times but still really don't understand whether it's possible or not.

i have a 2011 Peugeot 508, (no touch screen, navigation stick in the middle of the seats, moves letters on the screen, no post codes)

When I click on the software version it says 2.07.A3

I still cannot work out if I can do an upgrade by myself without needing an expert re-calibration.

Please could someone tell me yes or no, and if yes, the steps involved?

thank you!
