Tomtom one problems updating
Know that all models within one range are almost identical, e.g.GOx30: 530, 730 & 930 are almost the same: the differences are flash size and EPT in the 930 (the GO630 is the odd one out). The GOx50 is like GOx40 (and the GO9000), the most most noticeable differences are FM & MP3, which are left out in the x50. The One series has differences within the series, as well as the XL series. ": TTuser makes hacked versions of the different navcores for special needs.They have 32MB RAM instead of 64MB in the other models.Loquendo TTS requires a lot of working memory, and 32MB is not enough in most situations.(Some entry level models do not accept an SD card.) If you put an SD card in a One or XL, it will replace the internal flash memory.
The instructions include distances, road-names, directions to major cities, etc. Part two are splash screens with a sort of very simple windscreen view.
Tom Tom info on SD cards: (this info is based on the original configuration) "My SD Card does not work": You did buy a class 6 card, didn't you? You also need a recent bootloader (comes with a recent navcore).
Some problems on the SD card make the TT refusing it. See the Tom Tom site for details: These tools do not fix all problems.
As far as I know, all modern navcores/bootloaders support 4GB SDHC cards. A Class 6 card is essentially required, a read-speed of 133x works fine (if you want to know the difference, consult wikipedia).
I recently had good results with navcore 8.410 & map 8.25-2157 on a 100x read-speed SD card.Replace your old zip folder with this one (or replace the contents with the new contents).
