Hi - agreed.. I think it is a preloaded app. Vodafone Business seem quite helpful so I'll see what they have to say tomorrow. If all else fails I'm due an upgrade anyhow so I'll just get another one... I was waiting for some cool new unit to come out but looks like the 8230 is all there is.... and I can't see the point of having WiFi but no Nav - I use the Nav all the time.
