Nice, maybe I'm not as loony as I thought after all Thanks for the voice recommendation, that would get annoying.

And yep I upgraded to 2008 (wayfinder is bundled/installed with the OS already btw), then just clicked on the RHS of wayfinder and input my 770 Nav kit serial number. I already had the maps downloaded and saved on my SD card from using wayfinder (without routing) in the OS2008 beta though.

The repositories are taking a beating at the moment, i'm finding it impossible to install any other software at the moment, so my 2008 install is very much bare bones.
