If the Pod Go is on firmware v 1.40 and the G10TII is on v 2.0 it doesn't see to sync. What I had to do was downgrade to Pod Go v1.22 then update the G10 to 2.05 then I upgraded the Pod Go again to 1.40. This fixed it for me. As for charging I just got it and haven't had it long enough to charge completely yet. TO not this may also be something with Pod Go v1.30, but I haven't tested it.
