Make maps fit

I have the problem that the maps I need are bigger than the free space on the navigator. Any way to make them smaller?

Delete order: on your own risk

No RDS / TMC / IQ needed, delete "tmccodes.dat" and "traffic.dat" in your map folder (~ 5Mb?)
12.
Great-Britain.postal.ver and Great-BritainPostal.ver from the zip ~ 8.75Mb folder (navigating to the postcode in England is no longer possible)
13.
Backup-TT_Vista.exe Backup-TT_W7.exe Backup-TT_XP.exe PACLIB.dll PACOMP.dll
Delete all these files.
14.

With TomTom without a microphone you can delete the cspeech files (if you have a map with cspeech files at least). This quickly saves around 100 MB, depending on the card.

NOTE: You could possibly delete the. \ Helpme folder ~ 3.17Mb. . . (not handy if you need a doctor or hospital on the way).
