I am considering buying a Garmin Forerunner and was wondering what were the differences between the 405 that is currently out and the 405CX which is coming out soon. From the Garmin site, the only differences seem to be colors, heart rate based calorie computation, and the option to buy it with or without a heart rate monitor. Were their any other improvements that would be worth it to wait for the 405CX?
Thanks in advance for your responses.
