Not really official, found via @navigon_ on twitter, but the navigon photostream over on flickr has some interesting looking updates for version 1.2. From the looks of it you'll get proper iPod control from within the app (yay!) with a very cool 'peel away' interface for it, location sharing (great for stalkers), text to speech for street names (yay), automatic night mode (yay), and lane information in a small display.
Gotta say that these are some pretty nice things, and while they should have been in there from the start, they weren't absolutely critical, and make a nice point release update. Course, I'll have to nuke a bunch of music from my iPhone, then update, and then re-load it as I keep it pretty chock full....
No ETA on the update though. Also they only said these updates were on the European version, but I'd assume the changes will be the same across all versions. There are some more stuff on the navigon site about this too.
Update: A little birdie told me that the 1.2 update for North America and friends are already submitted to the app store.
