Looks like both TomTom and Garmin might be having a bit of a bad day to put it mildly, thanks to the announcement of Google Maps Navigation. As the graph shows, things are not looking good. Nope. Not at all.

GPS makers can at least take some comfort in the fact that the new Google Maps Navigation is available on Android 2.0 at the moment, which requires you to have a specific phone to download the maps real time. It will be interesting to see what happens next.
