How to change the email address / account name for a TomTom

Android apps.
In a thread that is locked to non-moderators Andy suggests that having a TomTom device connected to a computer will be necessary or helpful when the computer is making a web connection to alter a TomTom account. Andy, can you explain how any browser session will be affected by having a USB connection from the computer to a PND?
The reason for having the TomTom connected at some point is that the account name gets written to the device itself (have a look at the "ttgo.bif" file if you don't believe me).
I'm not sure exactly when that occurs, but my list of instructions closely follows TomTom's own directions.

Possibly the name only gets written to that file when you log into LIVE services on a Live-capable model, I don't have a non-Live model in front of me to check.
(And who knows how newer NAV3 models handle it!)
With a closed file system, who knows???
Clearly running Home or MyDrive can give a computer access to an attached device and its file system, but my question referred to a plain web session made and used for account maintenance that I believe you had been describing.
I am not sure it is an ironclad rule that a log in is written to the device. I have checked the ttgo.bif file and a log in name is not always written to it. If you logged in to Home, Home will sometimes write the email to a tthome.bif file. Sometimes it writes it to the ttgo file, but not always. I hooked up a 540 XXL TM today that I had registered last month for the lifetime map updates but did not have the time to update until today. I checked the ttgo file before I signed in to home (because I had forgotten the email) and no email addy was written to it. I use an older version of home, 2.7. But the minute I booted Home, it auto displayed the registration email. So it may store it on the PC, or it may store it elsewhere on the GPS, but it was not in ttgo and there was no tthome file. I later found the email, because I always write them in pencil on the box and use the same password on every unit I have ever registered, just to unclutter things.

I am not sure if you're asking to change the email on the map account or just change the email to get regular updates. TT customer service will change the email addy on a map account if you have the email and password and the map voucher code. At least they did for me.
