Just modified my parser to dump out all unknown fields that I'm seeing from my Garmin 800. For lap messages, I'm seeing 4 unknown fields that aren't in the SDK: 27, 28, 29, and 30.

Will there be an updated drop of the SDK with these values in it? In lieu of that, names of the fields would be helpful ... thanks.

I guess these are lat/lons of the north east and south west bounding points of the lap's GPS track.
You can try and compare the lap and session messages. The two have many equivalent properties.

Looks like your hunch was right. Thanks!

Still some more missing declarations for fields and records. For example, I see:

DeviceInfo record has unknown fields 8, 9, 15, 16

Unknown record #22 with fields 0-9 all of which are Type 2 with the exception of field 5 which is type 0. It has a TimeStamp field #253

Unknown record #72 with these fields:
3: type 140
4: Type 134
1: Type 132
2: Type 132
0: Type 0

Session record with unknown field 45

All of these were generated by a Garmin 800.      

Yep. I've seen these for ages - and it hasn't been covered by the FIT specs ever since.
