ONE XL seems to be extremely 'picky' with truck navcores.

My experience with friend's ONE XL (4S00.000), NC 9.7O1SE+SW:
- x50 emu: freezing on startup
- x40 emu: no voice (cca 8,5 MB RAM free)
- x30 emu: no voice, no "Clear route" icon (cca 6,5MB RAM free ?)
- oneiq emu: OK at 1st, then it may freeze after standby/reset (cca 4,5MB-6,0MB RAM free)
- xliq emu: freezing

Finally, used DSA to install 9.701 CAB in SELF mode only (cca 7-8MB free RAM) - all OK.
