Summary: Set up: The set up is really easy. I recommend you buy a stereo wiring harness for your car. That way you won't have to cut any wires in your car and you can always switch back to your stock (if upgrading from stock) stereo for what ever reason. I installed this in a Toyota Matrix and the wiring harness had the same color/wiring diagram as the Pioneer stereo, so I just had to match the color and solder, not sure about other manufacturers.
Summary: i was skeptical to buy this product, but after receiving it, it is worth every penny. This is a very powerful piece of equipment. Set up was easy and its very straight forward.It has many colours to choose for the illumination and boats clear and quick connections.The only downside is that i cannot seems to program preset radio stations, it scans and picks up whats available , from the manual i've tried changing but it hasn't worked, either way still a great buy.
Summary: This is the second DEH-P8400BH unit iv'e purchased i loved it so much i put one in the girlfriends car to replace the factory junk. Cant beat a pioneer head unit I.M.O. This unit does not start to distort tell a few clicks from max and i like that. only con is its not android friendly but works well via blue tooth. Seems like everything out there only caters to iphone.
Summary: The hands free blue tooth is terrible, I cant have a proper conversation with anyone using it, I have to yell, they seem all garbled. Does not work with my ipod touch ( thats all I have used it for) Not compatible with android. Using the radio is a PIA, getting presets is awefully difficult. Does anyone want to buy mine???
Summary: The installation and operation of this unit all went very smooth. The connection to a Bluetooth phone (Samsung Galaxy Note 3) was also very smooth. The audio sounds great. I have read complaints of the functionality, I don't really understand these. There is a selection button, a left and right/up and down toggle, and a back button. It is no different than any other receiver...but I guess with many people any change is bad.
