I have the TV which is the one you circled in the picture above but unfortunately the DVB-T does not work in NA. I remember you mentioned that you got the TV working. Now, what type of antenna did you connect and where? On my units the tv cable beside the IPod cable. The connector is similar to the gps connector.

For the mic jack, not sure. Hopefully it is for the mic. As I said I don't have the new model as you have. I hope to get my new units this weekend.
