Just tried a business address and a home address and both worked flawlessly. Well almost, I have a GO 630 with Home 2.5.1.36 and every now and them Home 2 will throw an error "Navigator failed to initialise - Code -9000" when I select Operate My Go. My only way to get it to work again is to uninstall TomTom Home, delete all references in the registry, the default folder locations "x:\Documents and Settings\(your user name)\My Documents\TomTom", and delete all shortcut references. Do a fresh install of Home 2 and make sure that when it first starts up it asks for your country, if it doesn't there is still a trace of the original somewhere that has your user credentials - find and delete and repeat entire procedure. After your done and you select your country Home should ask to download a needed file, do so and all should be well.
HTH,

Update: For whatever reason the procedure I posted to "Operate My Go" no longer seems to work. Somewhere there is a trace of Home that needs to be removed that I haven't located since uninstall/reinstall keeps my TomTom login info. I'll keep playing around and will update this thread with any findings.
Update 12/11/08: Found it!! Besides the above steps to remove TomTom, the stored profile must also be removed. This can be found in "x:\Documents and Settings\(your user name\Application Data\TomTom". Just delete the folders and "Operate My Go" should work.
