I just talked to the Pioneer dealer who installed my new X950BH, and this was a new one to him. He referred me here. The problem is similar to the Nav while driving issue, but relates to the tunes on my micro SD card. The system will not let me change folders while driving. That means that if we're on the road, listening to one artist, and my wife wants to listen to someone else, I would have to pull over!!! That's just stupid! I don't have to actually apply the parking brake, so I'm not sure the usual bypass is the right answer. Has anyone else run into this, and how did you fix it?
