Thread: Navcore v9.541 SE for One/XL 32MB by Tonyzeta

This was the forum that did it

I wiped my UK maps trying to update the firmware....it's been difficult to get them back. What I wanted was the gps to work as I lost the gps after a reset. I didn't care about it working as a sat nav, I just like buying old tech and seeing how far it can go in terms of modern usage....but alas it became an obsession. Mine is a TomTom One new edition and I bought it for a tenner. The crucial mistake I was making was extracting the maps files to the root of the SD card, not the folder with the files in it.

My GPS is working, I've upgraded the card to 8GB and can now use the latest maps and realised TTActivator will do all that for you. It only took me about 30 hours of constantly making mistakes and tears. One new battery away from glory. Didn't realise the significance of the bootloader trick. I don't really need 8gb of space for UK maps, but the moment I could only use a 2gb card I felt I was somehow being cheated

So:

1. Get an SD card 32gb or lower. Format it to Fat32.
2. Download the appropriate bootloader for the device and place the 'system' file on the root of the SD Card
3. Download the Navcore v9.541 file extract the files and place the contents of that folder onto the SD card, not just the folder itself
4. Put the card into the device, let it boot to the menu then turn it off again
5. Find the latest map you want and place the main folder on the SD card
6. Use Fast Activator or TTActivator to update meta, activate maps, activate navcore
7. Install the TT Home Windows program, connect the TT to the pc via usb and start the device allowing it to connect to to computer.
8. Do all the updates until it will accept no more updates. You need the "voices"
9. Find the "ephem" folder on your SD Card
10. Find the appropriate QuickGPSFix update tool and extract the exe to the "ephem" folder on your device. The latest I found at the time this was posted was "QuickGPSfix_v4.76.zip"
11. Run the appropriate QuickGPSFix update tool. Run it every 7 days after as well
12. Google "ttconv-v11.zip". Extract the zip file contents onto the root of your SD card
13. Boot up the device, go through the setup process, find "Status" and Information" press that, then "GPS Status". Leave it for 30 mins to find some satellites. Next time you turn your TomTom on it should find those satellites quicker.

I'm not sure if you need all the stuff in those steps, but it won't do any harm. The advantage of TTActivator is it will find and download the maps for you, and has other things of use in it. You need to go into "tools" update the meta and patch the navcore then go back to "installed content" and patch the maps

Tools sometimes throw up false positives on your AV. Use only trusted sites and don't download anything you don't own. These sort of hacks are simply to make obsolete devices function. "lifetime maps" should be lifetime maps. For the old TomToms you can buy a card for a couple of dollars on eBay...then use whatever SD card you can get your updated maps on and frame your too small SD card that you own. Piracy is using property you don't own, not making what you do own work because an original supplier broke their contract with you.
