Hi, new to the forum and thanks to this forum, I just finishing installing my z120 this weekend, did the bypass...[not completely working , need to check my ground], but after playing around with the unit for some time, there were some things on it that I felt was odd...maybe some of you gurus on the board can help me out here.

-When I use the BT, music is still playing regardless if I call someone or if someone calls me.

-When I try to watch some videos from my SD card, it doesn't play, what format does the AVIC read? I've tried avi & MP4?

-Is the Musicsphere only for the iPhone/iPod/apple stuff?

Switch the voice mute from ATT to MUTE ALL in the navi settings.

As stated on this forum many times, the SD/USB support on these units is poor. Especially for video. There is a thread or two on here where someone was able to get it figured out but several people still have problems getting it to work properly. Search the forum for details. Also, keep in mind you need to look for threads that deal with the Z110.

Yes.
