TomTom Map Downloads - retain camera warnings?

Does anyone know where the equivalent to mapsettings.cfg is on a Carminat Tomtom? It was quite an arduous process setting up all those warnings...

For that matter, is there any way of editing POI warnings other than in the car, live?

Does your Carminat have an SD card thats removable from the top right side of the screen? If so pop it in to a card reader connected to the PC and use Windows Explorer to views the files and folders on the card - Mike

For Carminat the mapsetting.cfg is not immediately visible as a single file. If you try to simply exploring the SD card you will never find it Wink

The mapsettings.cfg file (together with other settings files) is inside a file called either ext3_loopback or loopback.ex3 (for newer versions). This is an image file (Loopback Device file system image) that can be opened and modified in a PC only if you first add ext2/ext3 support and then mount the image as an external drive.

Using Linux (ext2/ext3 are linux file system so they are supported by default) you need only to mount the image as an external drive.

Interesting!

Would you be prepared to write that up in more detail as a tutorial? Maybe with a few screen grabs?

My first questions, not having seen it in action are:
Once you've opened the image, is MapSettings.cfg there in all its glory?
Would it be possible to edit it and re-encode the image or is that ext2/ext3 support read-only?

Yes once you open the image file, mapsettings.cfg is just a normal file Wink

and so are the other files contained in the image.
In fact the ext3_loopback (loopback.ex3) image file contains, besides the mapsettings.cfg file, also all the other usual "settings" files, like ttgo.bif, CurrentMap.dat, MapUserPatch.dat, etc. etc.
The image file is located in the /loopdir/ folder

Using Windows, just to read the files, you can use explore2fs, a little freeware program:

In order to have read/write capabilities, you must add ext2/ext3 support in windows... and it becomes more tricky.
BTW the procedure is the same as if you want to read a linux partition you may have in your hard drive.

One way to do it is to use fs-driver
http://www.fs-driver.org/

and then mount the image using one of the (free) drivers avalilable here:

The FileDisk-17 driver works perfectly.

If you use Linux it's all more straightforward as you just need to mount the image file (using the command mount)

Thank you!

It's no use to me personally, but I'll bookmark it and hope to pass it on to any Carminat owners whocome looking for the info (Dennis?).
