I tried to update the maps on my TomTom ONE South Africa. It downloads it fine but when it gets to installing it on the device and writing it to the memory card, an error message pops up
ERROR: HomeBase/IO: Error writing file: F:\helpme\other\travelinfo\index_nl.html
return func.apply(obj, arguments);
Time: Fri, 06 Apr 2012 21:27:04 GMT
and it will not let me bypass writing this file and carry on with writing the rest
Can someone please advise me as to how i can solve this and update my device

The Home Base I/O error means the pc is having a problem writing to the flash memory. Since you have downloaded a map and it is safely on your pc, the next thing to do is:
1. Format the flash memory
2. Reinstall the applcation
3. Reinstall the voice or voices
4. Install the map.
The only thing that concerns me is that the folder the pc was trying to write to ":\helpme\other\travelinfo\" is not usually included with the map download but with a application installation.
I would first recommend trying to backup the gps using windows explorer. Here is a link for the procedure.
Next confirm that a copy of the map is installed on the pc. Start Home without the gps plugged in and go to "Manage my Device" -> "Install items from computer", look for the item "Maps" and verify that it is there.
If you do have a map go ahead and format and reinstall everything per this link.. Note that part of these instructions will have you copy the map from the gps to the pc. Skip this part because you already have a copy of it on the pc.
Last, If the gps is working now, there are a few misc files like startup / shutdown screens that you can copy back to the gps from the backup copynyou made. Here is a list of those files. Just use windows explorer to copy them from the main directory of the backup to the main directory in the gps. Do worry if you do not find all these files are not on your backup. Not all gps models have all these files.
1. antitheftw.bmp (this may have the named antitheft.bmp)
3. splashw.bmp (this may have the named splash.bmp)
4. suspendw.bmp (this may have the named suspend.bmp)
Favorite destinations: If you want to recover these you may find them in the backup copy. The file is named "mapsettings.cfg" and is located in the map folder. The map folder's name will be similar to the region the map covers.
Example North America is name USA_Canada_Mexico_P. Copy mapsettings.cfg to the same locate in your gps.
If everything is working ok now we recommend making a final backup of your gps. That way if something happens in the future all you have to do is delete everything on the gps and copy the backup to the gps and you are done.

There a lot of stuff here to digest and do.

Traylaw, Thank you very much for this detailed explanation on how to sort out my problem... i really appreciate it.
I just have a few more questions regarding the procedure...
firstly i wasnt able to do a 'full formating' of the device and just did a quick 1 instead but that seemed to work fine.
I have done most of the tasks in ur explanation but the last thing for me to do is to add a map to my device. Now that is the whole thing that i was trying to do in the begining and i would like to make sure that i have the latest updated South African map. How do i ensure that the one i have downloaded on my PC is the latest, it says v730.2001.
Do i also need to add the 'map overlays' and 'quickGPSfis' to my device?

Ok, but I am a little surprised that you could do a quick format but not a full format.
The map is actually a folder of files, the folder will have a name similar to the area of map coverage. Example for North America the folder will have a name USA_Canada_Mexico_P. In your case it will have a name with S Africa in it. Below is the directory in the gps. Don't worry if your gps's is not exactly the same because the directory of different models will vary a little.
If a map update was downloaded to your pc, it will be stored in Home's download folder. The path to this folder is this.
There are a couple of ways to transfer a downloaded map to your gps. You can use Home ->" Manage my Device" -> "Install items from computer" or manually install the map.
To manually install the map see this link for the details.
The current version of maps are 885.xxxx. You can check the version number of a map by clicking on "More Info" in home for a "map item"
The version of the map installed on the gps can be found by going to "Change Preferences" -> " Version Information"

Map Overlays: You can install these if you have the space on the gps. It is not necessary.
Quickgpsfix: This is a set of files that are used by the gps receiver chip, it is not required but will cause the gps to "lock on" to the navsats and determine your position faster. The only thing is that the data is only good for about a week and then you need to update the information again for any benefit. The data in the files are basically the orbit information of the navsats for the next week. Without this data the gps must wait for the orbit data to be broadcasted by each navsat it sees before it can calculate your position.

Thanks again, however when installing the maps this error occured
ERROR: HomeBase/IO: Error writing file: H:\Southern_Africa\cname.dat
return func.apply(obj, arguments);
Time: Sat, 07 Apr 2012 15:45:18 GMT
now what does this error message mean?
08-04-2012 12:11 AM
Well that's basically the same as the orginal problem. There is an area in the flash memory that does not want to be written to. . When you format (FAT32) the gps's flash memory what is the error message you get? You may be force into trying a low level format.
08-04-2012 08:56 AM
it just says "windows was unable to format the device"
also when i connect the device it pops up with a screen to scan and fix my device or something, when i initiate it, it completes it succesfully and tells me there are no errors so its very confusing?¿

Where did you get the map .cab file? If you unpacked it for your Home's download folder, there is an additional file you need to unzip and place in the map folder. The would be the activation file. Here is a link with the details to manually install the map.
Also if you did install the activation file and still have a problem... try running TomTom's "Clear Flash" tool. Run the utility three times on your pc with the gps connected.
