C1.) Does the Colorado have a 2-axis or 3-axis compass?
The Colorado has a 2-axis compass similar to the 60cs(x). The unit must held horizontal and the compass must be calibrated in order for it to work properly.
C2.) Can you turn the compass on and off?
Yes. The compass can be completely disabled or it can be put into "auto" mode. Setup->Heading->Compass->Off will disable the compass, Auto will enable the compass below certain speeds, see FAQ below.
C3.) Is there a dedicated button that will allow me to turn the compass on and off (like the 60csx)?
No. You have to enter the Setup->Heading menu in order to enable/disable the compass.
C4.) In "auto" mode can I configure when the compass turns on/off?
No. In auto mode the compass will turn off if you are moving faster than 10mph (16km/hr) and turn on if you are moving slower than 10mph (16km/hr) for 30 sec.
C5.) Does the compass support both bearing and course mode?
Yes. Select either Option->Course Pointer or Option->Bearing Pointer to toggle modes.
C6.) How does course pointer mode work?
The course pointer mode will display your heading like the standard compass mode. However, the course pointer also allows you to establish a course by going to a waypoint or using Sight'n Go. Think of the course as a stationary line between your destination and the place where you established the course. Once the course is set you will get an indication of the distance and direction to the course (broken segment of the red arrow on a scale) and direction (red arrow head) of the original course. A blue arrow head is also visible, this pointer indicates the direction to the line that is perpendicular to your course and passes through your destination waypoint.
C7.) On the map page my cursor is spinning or on the compass page my pointer is spinning out of control, why?
You probably have the compass in auto mode and you either aren't holding the unit horizontal or the compass is not calibrated. You have the option to either turn off the compass or calibrate and hold the Colorado horizontal.
C8.) Does the Colorado support Sight'n Go?
Yes. The feature works similar to the 60csx. If you have the electronic compass turned on you can lock course in a particular direction and can navigate in that direction either by using the compass in Course Pointer mode or by projecting a waypoint.
