Maximum memory on SD card for Tom Tom ONE?

I am a new owner of a Tom Tom One, and wanted to know what is the maximum addressable external memory (SD card) on the device.  I know that 2G and even 4G cards are out there, but will not work if those memory locations cannot be addressed by the device. I have an advance instruction manual, but this issue was not addressed.  This issue came up with my Palm Tungsten E2, and that was settled at 1G max.

New purchased North america map.

I am assuming that, without being a GEEK, you are sufficiently proficient with a computer. I will describe the procedure with all the necessary details. I use Windows XP and all folders I refer to are in Windows OS hierarchy. I have tried all except starting from the SD card, I happen not to have a 2GB card ready.
I suggest you read the whole post, think about its feasability from your point of view, and proceed from there. If you have any misgivings about what I say, DO NOT DO IT. I shall NOT BE HELD RESPONSIBLE FOR ANY DAMAGE TO YOUR GPS.

First of all you should install the HOME application on your computer. Then you connect your GPS to the computer. When it asks you if you want to connect to the computer tap YES, and the HOME application will launch. You may let it perform an update (if any ) of the OS (application that manages the GPS). Do not let it make any update of the OLD map. On each screen you have a CANCEL button.

Use the TomTom Home Application to backup your device. The backup will be stored on your computer, and you will be able to restore it in case of a problems.

Disconnect your GPS and insert the SD Card in slot. Then connect the GPS to the computer and let it communicate with the HOME application.
When HOME launches it will show you the internal memory of the GPS and the SD card and you are asked to select from where to run the device. Select the external SD card.

If any thing goes wrong STOP.

In the main window of the HOME application use the right arrow to go to go to Backup and restore icon. Click the icon, HOME will restore the application and the old map, all that is on the internal memory.

If that does not work, I think you should copy the content of the backup folder \My Documents\TomTom\HOME\Backup\GO\Backup01 on the SD card. and try restarting the system from the external card.

What remains to be done is to look for the new map and put at the right place in the HOME folder.
Here I will show you the directory hierarchy in WindowsXP
On my computer the map is
\My Documents\TomTom\HOME\Download\complete\map
In this directory there is folder called North_America_2GB. It contains a 1kB activation Zip archive file, a 1.5GB map zip archive, a 6kB table of contents (. toc file) and two image files.

Once the application and the map are on the external SD card you should be able to start the device from the internal memory or the SD card. When you turn it on you will probably see two icons (one of the internal mempory and the other for the SD card) . They will be flashing for a short while. You have to tap the one that you want to start with.

I bought the new maps from website, and can not install

If the software crashed whilst updating, you will find that if you try to restore from a complete backup when you switch on next time it will either say you cant use the map or will just freeze, fix re format both the internal memory and the memory card, then find where tom tom home had stored the files, then using windows copy the contents from the 2 folders back into the relitive internal and external card, you will then find that you will get the mesage that you cant use the map, this is because tom tom home doesent always put the map data into the correct folder, to fix this find the licence data and the map data that has been stored on the sd card instead of the internal memory and copy it into the internal memory, before switching off press the reset button, when you switch on you should find that you have a working tom tom

When I switch on my TomTom, SD card has a red cross?

This problem is due to the memory card not containing the TomTom application or map. To update the application onto the memory card, Connect the device to your computer. Open the TomTom Home application. Click on 'Update My Device'. This should then install the application onto the SD card. Alternativly, you could perform all the steps above without the SD card in the device, this will install the application onto the internal memory. Note: you may also need to install your maps, voices, etc after you update.

Memory card

Replace the SD Card.

Unfortunately not all card makes are compatible. ie: Tesco own brand being one

Good and reliable make is KINGSTON

Put your dodgy card into a pc card ready, copy and paste the data onto the new card.

If that doesn't work then I would say you have a tempromental card reader in your SatNav and need a replacement.

Let me know how you get on.

Lost my memory card for my tom tom one

It's a standard SD card that you can buy from electronics or camera stores. Probably 1Gb is about the right size.

Tom Tom XL

The One XL can only read from internal OR sd card...
So, if you want the device to boot from the sd card, it need system files installed on the sd card...

So, try this:
- Copy ALL content from internal memory to sd card.
- Insert sd card, and boot the device.

It should know boot from sd card, not internal memory...

Max. Mem. Card

I think you will find that the tomtom one 3rd edition is a sealed unit.
No SD slot.
But it does have 1GB of RAM for storage and 32MB RAM for system use.
Pretty much the same internal architecture as an early handheld PC.
All updates are done through USB.
Hope this information is useful.
