New map (V9.10?)

Hello,
Next week I'm going to Italy and I want to update my TomTom One XL. Now I've downloaded the map Western Europe 1gb V910.4952,
but I don't know if this is the newest/ right one for my TomTom and my bootloader/ navcore.
Can anybody also tell me exactly how I can install/ activate the map?

By the way, here is some information about my TomTom from the ttgo.bif file:

I merged your two threads to show you that we
a) don't like useless doublepostings
b) that they are totally not necessary!
Before we even procede I leave it to you to clean your personal details out of your postings.
After that check the 910 map thread for all info's you might need.
