Why worry about carrying your iPod cable with you when you head out to the car? Use this CD-iU51 cable to connect your iPod to your Pioneer car stereo and leave your original iPod USB cable in the house. And you'll enjoy optimal charging speed when your iPod is connected, since this cable will work with newer Pioneer receivers with 1-amp USB outputs. This cable only supports audio playback — it will not transfer video to your receiver. Warranty: 1 year.

Why would I need an iPod® adapter?

An iPod adapter allows you to connect your iPod to your car stereo, then access your playlists with your stereo's controls - a great idea for several reasons. One, you can scroll through your song titles on your stereo's larger display, instead of squinting down at your iPod. Two, you can route the adapter cable to your glove compartment or center console, so your iPod stays safely out of sight. Three, the iPod adapter keeps your iPod fully charged, so it's ready to rock when you leave your car. And last of all, some adapters bypass your iPod's internal digital-to-analog converter, using your stereo's superior DAC to turn your files back into music.

Works great with my Pioneer receiver. It's pretty cool to just plug in my Ipod and throw it out of site and have all the controls at my receiver.

Pros: Easy install and use.

Cons: None.

Crutchfield Customer Review (What's this?)

This patch cord is a must have. You will experience your music from your iPhone or iPad like you never have. The clarity is incredible. Huge improvement over using a mini headphone patch cord. No more hiss just clear digital sent sound to your deck.

Pros: It works great

Cons: There aren't any

Crutchfield Customer Review (What's this?)

Keeps my regular USB cable in the house were it belongs. The thickness of gauge & insulation is ideal for transfer of sound quality & protection.

Pros: Love the length. I was able to route & velcro the cord down into my glove compartment.

Cons: None

Nice, but not absolutly needed...

Crutchfield Customer Review (What's this?)

This is a nice addition, if you have the money, but it is not absolulty needed for the install. You could probably just use your standard cable, that comes with the IPOD...

Written By John C, Wellesley, MA on Monday, December 31, 2012

Crutchfield Customer Review (What's this?)

After reading the other reviews, I was a little nervous that the cable would be shorter than the advertised 22.5". When I received the cable, it did seem shorter than 22.5" but when I measured it, it actually IS 22.5". Luckily, the head unit I purchased came with a USB extension cable which I ran from the radio to the glove box, then I just plugged in this cable into the extension. It is a very thick, sturdy cable which may be the reason that it appears shorter than 22.5". Works great. I feel like it is a little overpriced which is why I'm giving it 4 stars.

Pros: Very good quality cable.

Cons: Make sure you pull out a tape measure and see how long 22.5" really is and see if it will be long enough for your planned application.

Short iPod/iPhone usb cord

Written By Anonymous, Bakersfield, CA on Monday, September 17, 2012

Crutchfield Customer Review (What's this?)

Cord works very well but it is at least 1 foot shorter than really what it should be for the glove compartment hookup needed.

A real disappointment

Written By EricB, Whittier, CA on Tuesday, April 17, 2012

I'll say this - it connects the iPod to the USB on the back of my head unit, and it does indeed work. That's about it. The details page for this item say it's 22.5" long - it most definitely is not. 12.5" is more like it. For the price, you would be far better served going to the store and getting a real iPod cable - one that actually reaches somewhere you'd want your iPod to be!

UPDATE 12/12/12: I'm happy to report that the cable is extremely sturdy with a thick protective insulation. It has held up very well so far for me. Be sure to measure for this application however. If you have a front USB port on your head unit, this may be the perfect solution for you. If however, your USB is located on the back of the unit, you may find this cable to be too short without an extension cord.

Pros: Connects the iPod to the head unit, and transmits the signals like it's supposed to. Thicker wire insulation, cover on iPod connector

Cons: Extremely (almost unusably) short. Wouldn't reach from my stereo location to the glove box! Good thing I got a mounting kit with my head unit that has a storage compartment built-in, because that was literally about as far as it would reach. Way to expensive for what you get.
