For folks who have followed Garmin and its myriad of GPS navigation devices over the years, chances are you would have noticed the Colorado series. Sad news then as Garmin will be discontinuing the Colorado 400 series. Of course, not many will shed tears as the Colorado series never really took off since it always languished in the shadow of the Oregon touch-screen devices. Hopefully technical as well as hardware support will continue for at least a few more years before the original owners move on to something better if they haven’t done so already.
