i have a GO720 with 9.101 navcore with the default settings. My problem is, I can choose the line-out interface for the music, but it still plays on the internal speaker. If the line out is disabled could i see it in the sound options? Or if I would like to enable it, how can i do?

The other idea is to turn off the gps receiver sometimes, but playing music. I mean, I dont need the gps all the time, but wants to listen music. Is it possible, to turn off the gps not the whole device? I think this would keep low the energy usage.

Thanks and regards,
