I know the 735xt isn't supposed to have a compass, but it appears to. The heading data field works when there is no GPS or you are not moving. Anyone have an alternate explanation?
That's the way it works on a va-hr which has a HW compass. Start a non-GPS activity, and add the "heading" field, and it changes based on the 12 o'clock position (sitting in a chair and turning shows the direction you are facing). On a 230 (no HW compass) you get a "heading", but for me, always S or SE, even when walking north - the data is bogus...
Could it be the 735 has a HW compass that's just not mentioned anywhere?
From the CIQ view of the world (I know this was also asked about in that forum), it could be the HW compass data isn't included in Activity.info.currentHeading (you can get the info from Sensor.info.mag in an app, but can't access Sensors in a CIQ data field). (I just checked an app I have on the va-hr that uses GPS, Activity.info() as well as Sensor.info(), and when not moving, Sensor.info shows the actual heading when you look at the watch, while Activity.info seems to be showing the last GPS heading. When walking slowly in a specific direction, Sensor.info shows the correct data right away, while Activity.info takes maybe 20-25 feet.
In thinking about it, it kind of make sense, as it seems Activity.info is showing the direction you are moving based on GPS, while Sensor.info, the direction your watch is facing (think about when your arm is hanging free and not facing the direction you are moving - it would be wrong)

There are two options in the widget, use Position (GPS based) and use Sensor. Sensor is working for me. Despite the blurb at the top, magnetic is not an option (release notes say that magnetic option was removed in version 1.1.3):
The data can come from the position module where it is based on your movement; from the magnetic compass, where it is based on the direction you are facing; or from the sensor module, which seems to be some combination of the other two.
So if the sensor module is working on the 735xt, it must have a magnetic compass, agreed?

It means the Sensor Module has "mag" on the 735 (a HW Compass). See my post in your thread in the CIQ forum as one of the samples will prove it. If it does, it looks like I'll be adding it to "Hike 2" for the 735 (it's already there for the va-hr)

Hopefully Tim Grose will verify he has a compass too :)
Ok, so I'm all ready testing a "compass page" in Hike2 so I can display it on the 735 (I was able to squeeze in one on the va-hr but it too will now have a much larger one!)
Due to memory constraints I won't be able to do it for the 630 in "Hike" right now though...
In one of the recent firmware upgrades (4.20 or 4.30) Garmin updated the heading data field (Activity.info.currentHeading) to use the magnetic compass (as well as GPS).
