I updated my x830bt to version 4 and the unit is working fine - I can use my iphone 6 plugged into the unit with an apple 30 pin to lightning adapter, I can make BT phone calls.

But, I can not stream BT audio. When I click on the BT Audio button it shows that I am disconnected, and if I press the connect button, the unit pops up a window that says I have to initiate the connect on the phone, but the phone is already paired with the pioneer unit?

Has anyone seen this? 

Any suggestions?

UPDATE: I deleted and repaired my phone, and when clicking on the pioneer unit on the connection for the iPhone, I selected audio and handsfree, and now both the phone and audio functions work as they should.

My X930BT does this constantly with all of the phones I've ever used with it (Galaxy S Captivate, Nexus 4, Nexus 5). It will work fine for weeks or even months then it will decide that it will not connect until you nuke the pairing on both ends and do some sort of voodoo dance. It's driving me insane.
