No, I didn't look for the GPS info. Since the Uwatec data format uses a 
type/value encoding for the sample data and I didn't notice a new type, 
the only place where GPS info can be stored is in the MISC sample. I 
have seen some unknown subtypes before. A quick check shows there are 
indeed some unknown subtypes present in the G2 HUD data:

Unknown misc sample with type 24 and length 3.
Unknown misc sample with type 16 and length 91.
Unknown misc sample with type 17 and length 67.

I have pushed the changes now.
