lack of space on SD card for Speed camera software

I've tried to download the speed camera database. I extracted the files to a folder on my desktop and copied them onto the Tom Tom SD card, however there isn't enough space on the 128mb SD card. Is it only the OV2 files that I have to copy into the Great Britain Map folder on the card, or is there anything else that I can miss out so that it'll fit (and work!) on the SD card - Thanks in advance!

Delete some of the voices that you don't use. Better still get a larger SD Card.
You need the ov2 files and the bmp files.
