hello, can anybody help me with these questions: 1. Simplest way to read coordinates (for example. 31.8322607, 116.0742577) I do not need maps, so do not need to connect using wireless, only by GPS radio. 2. The A1 specs say GPS antenna is not supported. What does that mean? 3. The specs say Complementary GPS Services: Geotagging. What does that mean? Thank you.
