Traffic service needed before connecting?

[mvl]

Thanks for explaining the procedure. I was able to obtain the file as a .cab. I then proceeded to remove 8.351 using TT Home. Then I dragged and dropped the cab file onto the 730 desk image on my desktop. Then, while the 730 was still docked to the Mac, attempted to use it with TT Home, but no joy. It said that I needed an application in order to do this. I guess I should have tried undocking and re starting the 730 before it would work, right?

.cab is a compressed archive format, similar to zip. In windows world, I use winrar to extract the contents. I'm not sure what mac app can open it, but I'm sure google will pull up something.

The contents of this cab archive (files and folders) should be dragged into the tomtom drive.
