Favourites lost after map update

Every time I do a map update, I lose all my favourites and history. This never used to happen, and it drives me round the bend. I thought of doing a backup and then restoring it, but the implication from the restore is that is will overwrite the maps I have just downloaded.

There must be an answer to this - H E L P !!!

I believe that one of the advantage of POIs over Favorites is that you don't lose them when you do a map update.  Plus Favorites are limited to 48 per map.

This TT support article should tell you how to transfer favorites to a new map when you do an update.

When the favourites can't survive a map update, the favourite functionality must be classified as faulty and useless. Why doesn't TomTom just remove it instead of misleading the users.
OK, I'll try this next time, I've moved on. But I have the file. Fancy having a .cfg file that is not plain text. I feel a bit of reverse engineering coming on, at the very least something to extract the data for manual re-entry. If it is a database file (Garmin use sqlite, bless them) , the format will likely be open source, but there is no guarantee. Seem to be a lot of .bmp flying around during the update as well, I would hope these were compressed on the device. Gut feeling is TomTom developers have a utility for reading this file and are not sharing. At least the parts I want are readable to start with. Drum reset, gotcha, will test that soon.

Talking about the mapsettings.cfg file? And you copied it to the specific new map folder? (not a folder called 'maps', if present)

Try a drum reset on the unit by holding the power button about 20 seconds till you hear the drum sounds unless your model has a dedicated reset hole.
My .cfg file was preserved, and does not work. When I explicitly copied it back, it still doesn't work ! (ONE, 3rd ed.)

It should be in the backup. Just can't recall the exact location from the top of my head.
Thanks - I shall try that next time. In the meantime, I backed up my device before I updated it, in the hope that I could restore my favourites and home location! Is it possible to find these in the back up, or is that too much to hope for?

I looked both places.  USA_Canada has mapinfo.dat but no .cfg file.

Are you looking in a folder called 'maps' (wrong thing to look at) or a folder called USA_Canada (would be the correct folder to find the mapsettings.cfg file) ??

I have the NB1 (with some Favorites added) and use TT Home (ver 2.9.4.3058).  When I insert my SD card, Windows also opens up File Explorer so I can view the card's contents.  I can't find mapsettings.cfg in the maps folder - USA_Canada.tlv is the only file there.

 

I've looked around in the other folders too.   USA_Canada has mapinfo.dat but no mapsettings.cfg to be found. 

 

Is Home 2 different than Home?  I'm wondering if I can do this?

 

Thanks.

That would be good info to include in TomTom's "Find Answers" support page.    I'm going to try and remember this.  I've owned my TT for less than 2 weeks but I can see where my history would become more and more useful.  And this is much easier than the link I posted as far as getting your Favorites back.

Love these forums - Thank you!

It's true for all devices for which the user has access to the file system using Explorer (or Finder on a Mac). Or, to put it another way, devices that use Home 2, NOT MyTomtom.

Good to know.  Is this true also for the NB1?
