People, relax. The app has 1.3+ GB or data. We don't know how long it takes for an app of such size to get all the images updated. Other than sounds, pics probably makes the bulk of that data.
Besides, TomTom wasn't the first one to provide a turn-by-turn app for a reason. They take their time to make sure it's done right. Brand reputation is on the line if they don't, so again, relax. It'll be here at the right time.
In addition, it's not like the app just suddenly stopped working. Does it still give you directions without the update? Yes.
Let's just wait until they get it right. I'm sure it'll be worth it.
