Here's a few reviews of Pioneers iPod/iPhone connection cable and their Auto EQ Setup Microphone System. For some reason I couldn't start a new thread after being a member here for years. Sorry!
Pioneer CD-MC20 Review; I expected this Pioneer product to perform much better. I was hoping it would be of the quality of Audyssey's MultEQ XT found in some Alpine HU's. It definitely isn't in the same class. I am very familiar with auto eq systems from my Denon home theater as well as sound teching at my local church where we use the DBX DriveRack 260 Loudspeaker Management System. Both Audyssey and DBX have mastered Auto EQ technology.
I did the EQ process 5 times, twice at midnight to make sure no outside noise was captured. Each time the 7 min sequence produced the same results. The highs were ear piercing and very shrill. It did lift the soundstage, but it was unlistenable! Mids were hollow sounding and lacked any punch. The sub sounded disconnected from the sound stage and it was obvious the lows were coming from the rear despite both high pass and low pass crossovers remaining at 80Hz. I followed Pioneer's directions to the letter.
My vehicle is a 2011 Durango. It has amazing acoustics. The whole vehicle's inner sheet metal panels are dynamated at factory and inside panels are soft touch material. It's silent inside at highway speeds. When I manually eq to taste, using my Pioneer AVH-4300's controls, I can create a sound so real and lifelike, it's like being at the concert... lots of kick drum and bass punch, sizzling cymbals, perfect guitar and vocals.
With all that said, I have to give Pioneer a big fail for this Auto EQ System.
Pioneer CD-IU200V Review; I was very disappointed to find out after a lot of investigation that this cable only allows audio to be output through the 3.5mm mini jack. Pioneer doesn't tell you in their literature and it took a call to one of Crutchfield's excellent techs to determine this fact! They really know their stuff!
The 3.5mm mini jack is great for carrying the video signal but for some strange reason Pioneer chose the left/right audio portion of that 3.5mm jack to send the audio signal to the head unit as well. All new iPods/iPhones have an inferior DAC (digital to analog converter). The older models were much better. Because the audio file (MP3/ACC) transfer is basically the headphone jack output on the iPod, your expensive AVH Pioneer Head Unit doesn't decode the signal using it's very expensive and very high quality DAC. It basically amplifies the crappy iPod headphone signal! Music lacks punch, and is lifeless and sterile.
On the bright side, a direct iPod docking cable to the AVH's USB port will give you direct access to your iPod's MP3/ACC music files and it sounds great. Your AVH will still control the iPod and Album Art still shows on the AVH. Only problem is no video files will play.
Pioneer has to go back to the drawing board on this cable too. Why they couldn't have just the video portion go through the 3.5mm mini jack and audio go digital through the USB is a mystery!
