Maybe I must be doing something wrong or my cable doesn't work correctly

I have USB cable into USB2 slot, hdmi cable in

I see my phone makes charging sound, so does radio

if I disconnect, I can see where it says HDMI cable removed...

however, when I open App Radio unchained, it shows grey Bluetooth picture....I have unplugged and replugged the phone... sometimes I will see cable insert picture, looks like it will connect then android taskbar shows "disconnected"..... argh...

Bluetooth is already paired without issue... I did notice however for the phone it is not pulling any phonebook, etc...

I have a Verizon Note 2...

Ideas ?

I was watching a video on youtube.... I have disabled/enabled Bluetooth but the app doesn't try to connect automatically

if I go to settings in Bluetooth and connect to unit, it pairs, app says trying to connect then disconnects...

sigh.......

You should probably ask for help on the XDA Developers forum where Area51 can help.

Tagging this, I have the same issue where HU doesn't pull any Address Book data, as well can't get AppRadio Unchained to work so far.
