Garmin CFO Kevin Rauckman in an interview has said the company might back out of its smartphone business within the next half a year if it can't be turned around. He acknowledged to Reuters that devices like the Garminfone and nuvifone lines had undersold in the market and that the GPS maker would 'have to make decisions" as to whether it would redouble its efforts or back out. The company managed just $27 million in revenue from smartphones during the spring, far lower than competitors; Apple produced $5.33 billion from its iPhone business in the same period.
