Why do I have a 'called.txt' File?

[tom thumb]

I have a TomTom One v3 that has no bluetooth or any other way of making or receiving telephone calls, however I do have a /contacts/called.txt file that contains 5 telephone numbers, one is for a national railway enquiries number and the other 4 are telephone numbers that at locations within a mile or two of where I live (in the Midlands of the UK). So here's the question, how have these number got onto my TomTom?, I have never made or received calls to / from any of these numbers on any device and the only two-way contact the TomTom has with the outside world is when connected to the TomTom Home package on my laptop

Thanks for the reply, the link shows how to create your own contacts.txt file containing your phone numbers, however, I have owned the One v3 from new and no-one else has ever have access to it, I have not created this file, so it must have self-generated some how. I've noticed that some Points Of Interest, e.g. my local Mcdonalds has an address and a phone number as well as it's location on the display, I'm wondering if pulling up this info. adds the phone number to the called.txt list for some reason, it isn't of any use on this model as it doesn't have any phone capability, but I think that is where the list is coming from

Even while you have no BT capability on that unit, when you bring up a POI, is there the option to TRY to place a call to the number associated with the POI? I'm wondering if by chance that had been poked accidentally a few times over the life of the unit.
