Which NavCore for TomTom One

Hello,

Which NavCore should I take for:
TomTom One (4EE0.001.00 / N41644 Canada 310)

The system has 32MB RAM / 1GB ROM / BootLoader 5.5011 (No SD).
I'm looking for the smallest (and fastest/stable) one, to keep space for the map.. :-)

Thank you!

*) Update the device with TomTom Home to the latest navcore, probably 8.010 or 8.014
--
1) Make a backup of your Device and delete the map.
--
Copie the chosen map to your Device in his own folder.
If you open the map you see the loose files and probably a folder (brand).
Not a map in a map.
--
2) Copy "FastActivate.exe" to your TomTom device in the root
noref.php?url=http://linkcrypt.ws/dir/m24dq269u7183k4
Run "FastActivate.exe".
Select 2 and 3
Wait for the announcement navcore Patched.

Done
