Question about Tomtom GO 300 GPS Receiver

1 Answer

GO 300 not recognized by PC & Home / doesn't recognize SD card


I've done EVERYTHING suggested in your FAQs on two different computers and several different USB ports and still no luck. I hope you can assist as soon as possible on this one as it is very frustrating.

The situation is my boss lost his SanDisk for his GO 300 so I snagged a new one and re-loaded his maps, etc. Plugged the SanDisk into the GO 300, turned it on, and after a second the display shows the disk being removed from the GO 300 with a red X thru it. No biggie I thought - bad SanDisk. Picked up another one, loaded the maps, etc. again with zero issues, can see them in Files-Explorer, etc. but the same damn red X when I plug it into the TomTom.

Loaded the latest version of HOME ( on my PC and figured I'd troubleshoot that way. Downloaded the latest and greatest this morning, no problems, fired it up, and plugged in the GO 300. XP can see the new device but HOME does not find the TomTom. Switched to every USB port on the PC, still the same issue. The picture on the GO 300 shows the back of the TomTom with the cable plugged in but no other options. It never asks to 'connect to PC' or anything.

Did the same procedure on a laptop with the same results and now troubleshooting is pointing me to the TomTom as the issue. The Sandisks are fine, the cables are good (I've used a couple different ones), it's charged, applications are loaded fine with no errors, I've reset the device several times to no avail, XP can see it via My Computer, yet the GO 300 just sits there and spits out any good SanDisk you put in it and/or doesn't ask to connect to PC. It gives you the red X-remove the disk animation or the still shot of the back of the unit showing it's plugged in but no options to continue.

I've done everything remotely related that I can see on Support page. Please tell me what I can do to get this working for my boss again or if it's hosed and we're out a TomTom GO 300 box.

FYI I've also tried uninstalling the latest version of Home and using the earlier version of TomTom Home (as suggested on another site) but that hasn't worked either. . .please assist, anyone?

Thanks for your help.

    When I plug in my GO 300 it just shows a still of the GPS plugged in with no options. Both Home and my computer do not seem to recognize it. This is the first time I have tried to plug it in so it has never worked as far as I know. Tried all the FAQ stuff on the TomTom website to no avail. Called their tech support line to no avail as well.

WOW!! You have tried everything i can think of...I was going to have you go tan an earlier version of home, which you said at the very bottom....

maybe try this.......put the SD card in the unit and format it again....this time try to add a fresh application and 1 voice this straight from the home disconnect the device and hopefully it says 'No Maps found'. If it does then we know the drive is good..if not then the unit might be shot....if you do get 'No Maps found' into support and have them give you a frsh map...(If they ask, inform them exactly this--'I did not make a back up, all I want is any map, so as long as my unit is up and running"

Trying to updat rand McNally and it is sayin not able to detect card


Turn on your device. Turn up the volume to max setting. Insert the SD card. Do you hear a chime? If you do then the sd card has been recognized by your device. If you do NOT hear a chime then try another card. If you do not hear a chime with another card then there may be an issue with the card slot on the device. It would need to go to Rand McNally support for repairs.

If you hear the chime which confirms the card was recognized then connect your device to your computer. Go to the My Computer option and find the SD card drive. It should say something to the extent of "removable drive". Right click and select the format. Select the FAT32 setting and a quick format is fine. This is done to ensure there is no data on the card and it is formatted correctly.

Once the format is complete select Map Update from the dock. The dock should have no issues recognizing the card and downloading/installing the update.

If you are still experiencing issues please contact Rand McNally technical support.

Tried to update my Tom Tom One by connecting to my

Remove the SD card

The card needs to be formatted properly first that's all,

formatting is better done in a card reader.

Right click on it and select format select FAT32 as the files system

Update your device without the SD card.

Make sure your GPS runs OK without the SD card

Now re-connect the tomtom but don't let tomtom home run. exit TTH if need be.

You now ned to select your tom tom which will also show as a drive.

In windows explorer select tools then folder options.

Click view and tick the box for "show hidden files and folders"
It may warn you but you can ignore it.

then just copy ALL the files from the tom tom to your sd card


Once all the files are on switch off the tom tom and insert the sd card and re-boot
It should now work again

Why cant I download my waypoint data to a 2 GB SD card. My Global map 5000c does not recognise the 2GB SD card. Do I need MMC/SD. Can I place the sd card in the slot beside the chart card ?. Thanks

You can place the SD card into the slot beside the chart card.

With the SD card in the GlobalMap unit by itself (take the chart card out), press MENU twice and choose BROWSE FILES. Does the unit indicate that an SD card is present? If yes, the card is working fine in that slot. Try the same thing in the other slot. If it only recognizes the SD card in one of the slots, the other slot is bad and probably won't work with any card. If the card is recognized in the BROWSE FILES menu, but the data that is on the card is not working, there could be compatibility issues with the data and the GlobalMap 5000.

Make sure the GlobalMap 5000 has the latest software update from You might need to get a different, smaller capacity card since your 2GB is not working.

If the 2GB SD card still isn't recognized in the BROWSE FILES menu after the update, the GlobalMap 5000 is not going to work with that 2GB card. You will want to get a different card. I suggest 1GB and smaller.

If this doesn't help, please let me know some more details. Is the 2GB SD card recognized in the BROWSE FILES menu. What are you seeing that makes you determine it does not recognize this card? What files are currently on this card? What kind of card is it (brand, model).

Device not recognized by computer

Lots of folks having this problem with many different TomTom Models, mine was with a GO630.

Do a "reset" on the unit, use a paperclip or somesuch and hold the reset button on your TomTom in for about 5 seconds, and the unit will rrset and will be recognized by your computer.

IQue 3600 sim card problem

from Garmin:
Question: Why wont the PC recognise my the SD card in my iQue 3600?
--> Answer: Go to My computer and look for the following directory:

  • C: > Program Files > Palm > (user name) > file called 'sync'

  • Double click on this file and delete the four bottom rows that will look something like this:

DisplayName=SecureDigital (SD) Card

  • Then try a HotSync as normal, it should then 'see' your SD card.

  • If all fails delete a second user name as sometimes this interferes.

Problem loading maps to ubs card

The i3 comes with a 128MB micro SD card - first can you be more specific as to what you refer to as "not recognized"? Do the usb drivers install correctly and after installation is the i3 recognized by your pc once you hook it up with the USB cable? Is the micro SD card in place? Is it all the way in the slot?
