TomTom GO 300 and the TomTom One V3 without SD cards

Hi!

I bought a very cheap two TomTom GPS navigations without their SD card: TomTom GO 300 and the TomTom One V3.

When you turn on any of them, they search for their navigation SD card.

Windows 7 detects both devices, but I can not access the memory. TomTom HOME does not know that the devices connected to the computer.

Does this navigations can fix it?

Both your device does not have internal memory and only work with SD card.
Put in TomTom empty SD-card and update through home. (or to begin with-to test the functionality install on SD card software 7.903)

How to install on SD card navcore 7.903?

I tried the Copy/Paste, but no results. TomTom device does not see the SD card.

TomTom Home does not see my SD card and devices.

1-SD card up to 2 GB (great card your devices will not be able to see)
2-download-unpack and copy to SD card

3-put the SD card in the TomTom and TomTom start.If all right-that TomTom will see the SD card and write that no maps.
4-bear in mind, for each device you need a separate SD card

Thank you very much.
I am constantly trying with 4GB SD card, and I failed every time.
Now, Everything is OK.

In order to use 4GB or more, you must change bootloader to version 5.5022 or higher.
And another tip: you can install the software 9026_one and use the best maps (950_6492)
