A:Answer Im not exactly sure, i would like to think it comes down to the ios. With that said, I’m also not sure who it falls on, I would assume Pioneer, but there are some bugs that need to be worked out. When your phone leaves the bluetooth range, reconnecting leaves you with a glitch to where either your phone or radio will begin playing the song or station you were on and the other will not. It may go back to the song you initially began with, or maybe the last one it was playing at that time. Let me clarify, Im speaking of the pandora. Now, I must say, I have the Microsoft sync as well, so you have blutooth audio and pandora options on the Pioneer going on at the same time, plus the Microsoft sync with the Maestro chip trying to coordinate all this through a Apple Iphone. Im confused just typing all that lol. But, I have figured out if you simply pause the song on either the radio or phone, then press play on either it will then continue. It sounds more confusing than it is, though it was frustrating when I initially begun noticing the problem. This is only with the Pandora, so Im not exactly sure sho to place the blame on.
