TT XL 30 series, which navcore and maps :)?

Hello everyone!

I'm a newbie with TT XL 30 series 1GB 32MB RAM and I'd like to upgrade it to the best working navcore and newest maps possible for this tomtom.
Someone told me to use the navcore 8.562 SE (wat does SE mean?). Is that right, or is there a better one? I don't understand how to read the mapcharts I found.The only map I need is one that includes The Benelux and France (Western Europe?). And once I know which map I need, do you have to dowload all .rar files with the same map name, or just one of them? For example I see Benelux_990_8306, Benelux_990_8316, Benelux_990_8317 and Benelux_990_8365 (http://i.imgur.com/R7MIboe.png).

Please help me:)

My infoscreen on the TT now tells me:
Appl. 8.083
GPS v1.21, Boot 5.5136
Map Western-Europe-1GB v835.2420

1) Make a backup of your Device and delete the content.
--
2) Unpack the* navcore (winrar ) and place folders and files on your Device.
--
3) Reset The Device (minimal 15 sec) and start it till the announcement "No map found"
--
4) Copie the chosen map to your Device in his own folder.
If you open the map you see the individual files and probably a folder (brand).
Not a map in a map. You can delete the cspeech file in the map

5) Copy "FastActivate.exe" to your device.
