I was reading somewhere online how to do a hard reset. Not tried it but getting some info from TomTom direct could be of help to put your mind at ease. I tried the body composition earlier and it worked ok on the 2nd attempt. Didn’t work the 1st time for some reason.
I've emailed TomTom to make sure my data won't be able to be seen by any previous users, see what they say. By the way, have you managed to get the body composition function to work? I've tried many times but it just comes up with a cross indicating it couldn't get a measurement.
I think it can only be synced to one account at a time. I had to enter a code to sync it up to the mobile. I put in wrong details anyway as it wouldn’t let me input my son’s d.o.b as it only allows 2005 and back. I’m not worried but I get what you mean by them selling them as brand new.
Couldn't that mean the previous owner might now have access to your data? Name, email address, date of birth, gps location, call and text notifications etc. Bit worrying! It's really bad Argos are selling obviously used returns marked brand-new.
Just seen this and checked ours. We had the same saying it was linked to another account. We just ok’d it and it seems to be fine ... for now anyway. Just finishing off charging and will have a play about with it tomorrow.
