I'm just a regular guy when it comes to car radios. In my opinion. my z130bt is better than the newer z140bh. To me, the biggest problem is that the z140bh removed voice control inputing directions and finding POIs. I have no idea why they did this, but it is a fatal flaw. And since I don't care about Pandora, not much into Aha, and I don't have an Iphone, I don't see how the z140bh will help me. As far as speed, maybe the z140bh is just a little faster, but it's not such a big deal one way or the other.
I don't know if anyone else has noticed this, but I really think the z140bh is a DOWNGRADE from the z130bt. I am also seeing the prices for the 140bh dropping down and sometimes below the 130bt. I think Pioneer dropped the ball on this one. Can anyone suggest a reason for my keeping the 140bh and not returning it and getting a 130bt?
