Over the summer, navigation device maker TomTom announced plans to buy Tele Atlas, one of the two leading providers of mapping data. Earlier this month, Nokia announced plans to buy Navteq, the other major provider. That resulted in immediate speculation about how Garmin (TomTom's main competitor) would respond. Apparently, the answer is with lots and lots of money. Garmin has now put in an unsolicited bid of $3.3 billion for Tele Atlas, hoping to outbid its rival by 15%. So, at this point, a game of musical chairs begins, with Nokia, Garmin and TomTom fighting it out over the two mapping data providers. Since both TomTom and Garmin seem to feel that they need to have Tele Atlas, don't be surprised to see the price keep going up.
