Full update:
-TT bought Thursday, and worked great, even played with the features.
-docked on computer to load home and browse Plus. Tomtom would not power up. Looked on website, TT.com suggests that you do a hard reset in order to restore. (Because I had problems on the first dock, I have no backup)
-Performed hard reset which is how I arrived in the TT's current state of sometimes just a green and white outline of a TT, and other times an animation of the SD card coming out with a RED X
-Tried "Selecting Device", rebooting computer, rebooting home, powering off TT and docking then starting home and powering up. Tried soft resets and hard resets since then.
-Computer sees TT, calls it a mass storage device, but a TT go when you look at the storage devices properties. Device is enabled in Device Manager. Cannot format card through TT from XP. (I don't have a card reader either) When I put the card in the built-in card reader on my Dell Vista, it crashed Windows Explorer, and makes me logoff and back on. Vista will not boot with card in either.
-It seems that the TT is being all nicey-nice with the computer, but won't respond at all to Home. Therefore, I cannot use Home to install anything to the TT, and my TT has transformed into a nice paper-weight.
I think that just about covers it. I'm thinking I need a magical way to reinstall the software on the SD card w/o using home.
