I think the F&H should boot to menu screen, mine does. The WinCE registry in flash has probably been modified to boot directly to TT. Never bothered tinkering with the registry, but I have the registry editor somewhere if you need it... can't remember whereabouts in the registry you change the filename to boot to though, sorry.
I found this whilst googling, it's navigo related but could be relevant...

I reckon I've still got the menu/games stuff I found on simplesatnav, but I checked and it's definitely specific to the 4.3" widescreen model, iirc the games were ripped from another 4.3" ws device.
Not seen this stuff hosted anywhere else since simplesatnav went belly up.
