This is what happened to TomTom and Garmin stock prices when Google announced Maps Navigation. To be honest, that's why the stock market should scare companies not google. The stock price is an arbitrary number derived by people who do nothing but sit around deriving stock prices. Both TomTom and Garmin (hell they make avionics suites FFS)_ address different market needs from google, and I highly doubt either will see a dramatic immediate effect on their revenues. Long term, my guess is that TomTom will feel something, but Garmin is pretty secure on the high end.
