Audio issues iPhone 5 using usb?

This is exactly what's happening with my 5000, BT streaming works fine. After connecting my iphone 5 to the USB buzzing starts I thought I had a faulty unit. Now what I dished out a hefty amount for this unit and it doesn't even relay the music correctly and NO CARPLAY on top of that

The car play is coming in about two weeks and call pioneer to let them know. I called today to let them know they need a firmware update. Everything works perfect with my unit besides my apple products being installed into the USB. They need to fix that. This is my second unit already from Crutchfield thinking it was the unit.

My installer said he talked to pioneer and they know about the issue. They will have a future firmware update coming for the issue.

Tekki here you go pal. The same ignorant comment you made in this one and is now starting to surface for everyone. I tell you one thing pioneer needs to fix the issue.
