MyTomTom on a Mac

[susanp]

It doesn't matter.

If you have several devices that all need to connect to MyTomTom, it just seems to remember the last one you had plugged in.
When you plug in another one, it should recognise it (showing you a picture of it in the top right corner), but it doesn't automatically log you in like you could set Home to do. You have to log in with the correct user name for whichever unit is plugged in, every time.

many thanks will see how it goes.
