Since there are users out there that want more than the map area that came with the device, I started seeking ways of patching this new Navcore.
The workaround that could be used for the old Carminat Navcore no longer works for the new Live model.
Even if a patched PNDNavigator is used on the SD the device will still use a copy of it on the internal memory.
The internal memory can not be accessed due to no connections and the fact that it is based on TT's own Linux system.
Due to the input of some nice guys and a tester I can update all interested users with current state of this project:
Patching of the PNDNavigator is possible - at least no tool gives an error back.
Activating new maps is possible too.
To get the infos and/or the ttgo.bif the easiest way is to make a backup with Home and to open the created ttgo.bif in the backup folder located in the users document folder.
Ttgo.bif onto the SD, add the new map and activate with Fast- or AutoActivate.
Patching as until now is not confirmed possible.
There is a way to overwrite and update the internal memory but if that does not work with the current Navcore because the version numbers are the same, any user with a Carminat Live should not make the next Navcore/Application update offered by Home!!
If it is possible to update the internal memory with next Navcore version the device must not be updated by Home with the official version!!!
So if you get an update offered by Home don't install it and quit Home, after that inform us here that there is a new versin available.
I will try to provide a patched installable Navcore for the next update by TT but it will only work if the device was not updated with the original offered by Home!!!
Update22.01.2012:
The Bootloader as well as the Navcore kernel are protected by a 2048bt RSA key.
For that reason it might not be possible to patch or install a patched NC - needs further testing!
We have two kinds of maps supllied by TT:
1. maps that come with the device or are ordered on a SD
2. maps that come as an update or are purchased through Home
They differ in the type of activation.
You either find a DCT file or a MCT file in the map folder.
If you have a MCT than it means the map can be used on any device if the original SD is used - no copy of the SD will work!
If you have a DCT than it means the map only works on your device but you can copy the whole content of the SD on a different SD and it will work (in your device only!).
What does that mean for the current project?
Well, if you can not use a modified BL to load a modified Navcore it will be impossible to use self activated maps.
Same for the Kernel protection: If the device checks this RSA key to see if the NC is genuine that a patched Navcore won't be installed but instead the internal Navcore is used to rebuild the SD.
Cyber-Crack found a version info inside the NC and I created a patched version based on the 9.844 but with this version info changed to 9.845.

I don't expect it to work for the above reasons, but if anyone is willing to test it:
Unpack the archive onto a blank SD add your original map folder from the backup and insert the SD into the Carminat.
If all goes well the NC will be installed and show up as 9.845, if it does not work you only will see 9.844 - since it is not confirmed what this version actually does we need any tester who installed it to check:
a) if the original map works as before
b) if the map still works after you used a keygen for the activation (or a newer map that you activated).
Please report in this thread if you could make any progress!

Update: There are tools like the Forensic Toolkit (FTK) that allow investigators to access all sorts of drives on a suspects computer regardless of the operating system.
If someone dare to try to get access with those tools and a laptop we would need to know how to connect to the USB port on the Carminat Live.
Please use this thread for all problems related to patching and activation problem.
If you have questions about the access in Windows or you want to upload a working and patched NC for the Carminat Live use Tomtom-Carminat-Live-Editing-installation-files-on-Windows-PC's!
