Update map of tomtom one 4n00.005

SOURCE: tomtom one maps

I just had this same problem. Quite strange. I have a Tomtom One New Edition and connected to a Vista Ultimate computer. Here is what I did to fix the problem I was having.

Exited out of the Tomtom HOME application. Went to "Computer" and right clicked the Tomtom drive (was M: for me, could be different for you) with the Red Icon. Selected properties and click on tools. From there I selected "Error-Checking" and only checked "Automatically scan and fix errors for me". It said it found a couple errors and corrected it. I then doubled clicked the icon in the bottom right portion of my screen which looks like a USB plug with a green check mark on it. I selected the drive and clicked stop. I disconnected the usb plug and then used a small tack on the bottom of the Tomtom unit to reset the device. After that, I turned the unit on and all was fine and I could clearly see that an update was applied.

Good luck! They really should have a support bulletin for this as this is clearly a common issue.

Hi, I am a complete ignoramus when it comes to this sort of thing but I am pretty sure that you have the same problem I have, I updated my GPS just like you did because, heck, that is what TOMTOM recommend and hey presto I wound up with an application 'core' of version 8.x trying to access a map with a version of 7.x. Doh! You would have thought the damn install app would figure this out and NOT install wouldn't you ? Great, I barely know how to turn on a computer and I have to deal with this ****! My GPS unit is a GO 720.
Anyway the options were to fess up $100 for the new version map - or, um, well, patch it myself :-)
At this point I decided that I would patch it myself as:  a) I hold TOMTOM completely responsible for buggering up my GPS without warning and  b) I NEED my GPS right now, not whenever TOMTOM get back to me with a reply to my query about why this happened 
Here are the two links I used to patch my GPS, and yes it took a couple of hours to download and  sort it out.

Where it says...
For have a working map you must:
- Patch your 'ttsystem' file and 'Tomtom Home' with this tool:

Password: demonfatal
- Use the Keygen for patch your map
Keygen for map :

 (Note I selected this map and it seems to work Australia_815_2086)
The new map would not work until I replaced my 'ttsystem' file with the one from the link below - dunno why.

Remember to use TOMTOM Home to back up your current GPS settings/configuration in case you balls up the patching process - frankly I don't trust TOMTOM Home to do a good enough job so maybe in addition it would be a good idea to connect the GPS to your computer and use something like Acronis to create an image... 
good luck

I do some work with TomTom - it's possible that if something interrupted or went wrong during the install, the map could have been deleted. TomTom is aware of the problem and is working to fix it - if you are map-less, call support (866 486 6866) and we can work on getting you a new map.
