sorry to correct you but there is no update 'due out shortly'. the one in iTunes IS that update

I read their iTunes page, it does show an update which is available soon. I don't know why it doesn't show that on your iTunes link for navigon.
 
I'm not sure which you are talking about. iTunes (Canada) shows the latest update as Jun 18.

The US version is still v1.0, there is a v1.1 in the pipeline just like the v1.1 that is available overseas now.

Just like the initial release, the US version is lagging behind.
