Ub-100 on a Pioneer Avic-D3

Written By Claudio, Palm Coast, Florida on Thursday, December 10, 2009

Crutchfield Customer Review (What's this?)

I really wanted to give this 3 stars, but if does what it say it does. This item is a great add-
on if you you do not has USB in your head unit. The main reason why i got this was
because my nav unit is also flawed by not giving you full use of the NaV controls unless
the NaV disk is in.This play all my mp3 flawlessly my only gripe, like the rest before me,
is the id tagging only having 8 charecters suck. Some of my songs have the artist name
in the song title so it will say for example Green Day on all the song in that album.Also
my nav unit was not in the list of compatible head units so I dont all the features like
folder name, just song names.If a cheap 5 dollar china fm tranmitter can scroll 30
chareacters there is no reason for this not too! But all in all i am some what happy with it
it play my mp3s with out taking up my cd drive so yah.

Don't use with new head units

Written By Clyfton, Crestview, Florida on Thursday, June 11, 2009

Crutchfield Customer Review (What's this?)

I recently purchased a Pioneer DEH-P610BT which has only been on the market a few weeks. It has front USB and I wanted rear USB too. Unfortunately, the only way to get rear USB is with CD-UB100. I read the reviews and there just wasn't enough info to make a decision so I tried it. I'll give away the ending first ... I ended up returning it. The problem is ... any head unit will treat the CD-UB100 as an external device ... so the head unit just ends up being a dumb terminal ... losing any advanced features or functionality. Here are the CONs (there are no PROs):
- the new head unit has a feature called SOUND RETREIVER which enhances compressed audio ... this feature is DISABLED when played through the CD- UB100 (unacceptable).
- contrary to the instructions, I was not able to display the mp3 file name. I don't need to see the file name for every song, but I do if I want to know what a particular song is (unacceptable).
- this stupid thing comes with NO mounting hardware ... not even a bracket or a place to screw it into the under side of a dash. They expect you to velcro it to something (tolerable).

Bottom line ... only buy this if you have an older head unit with no USB and want to add USB. Pioneer needs to come out with something newer to go with their newer head units.

The End of a of CD Case

Written By Cliff, Phoenix, AZ on Monday, May 25, 2009

Crutchfield Customer Review (What's this?)

The product worked great after tweaking a lil bit. I hooked up a 250 GB hard drive which did after doing a couple things to make it work. First I had to format the hard drive to fat 32 instead of windows NTFS and then the supplied usb cable needed to be shorter in order to work with my hard drive. It sound like a little bit of trouble but not too bad at all. Just google for formatting of the hard drive and use the USB cable that come with your device should be fine. Like the title saids "the end of a cd case" because right now I have about have of my music on the hard drive which is about 8,000 song organized by folders. Highly recommended if you love a lot of music like I do. I the deck I have is Deh p7900BT.

Worked better then expected

Written By Robert, Oglesby, OK on Tuesday, May 05, 2009

Crutchfield Customer Review (What's this?)

I connected this to a DEH-P835R, which is about as old as it gets for being IP bus equipped. I bought the head unit in 1998, says a lot about Pioneer in general huh? Anyway, the CD-UB100 worked just fine with it and will display the first eight characters of the track title once set to do so. One down side is I can't figure out a way to make it display the folder name instead of a number when looking through the various folders, seeing Rammstie or Rob Zomb would be a ton better then always seeing USB F02, so if you have a massive collection it could get confusing, though as soon as the first song in the folder starts to play the songs name pops up. Navigation can be a bit slow with the more limited interface of this older head unit, but it beats a CD changer in the trunk by a wide margin. Being CD-UB100 won't recognize partitioned drives it doesn't see the 2 gig SD card that is plugged into my freebie 256 meg MP3 player. This upgrade to one of the older IP-bus head units is perfect for people with smaller music collections that want a very cheap upgrade to finally ditch CDs. For folks that insist on the burden of having a 1500+ songs in their mobile collection I'd recommend a new head unit with a built in controller to make navigation feasible. The CD-UB100 has been the best bang for the buck out of anything I have ever added to my system.

Just what I needed

Crutchfield Customer Review (What's this?)

My head unit does not have an usb port. That's why I purchased this item which allows me to connect an mp3 player or Flash drive.

Flash drive makes it a lot easier... just plug it and play it -
up to 250gb :)
It is awesome not having to juggle any more cds.

This unit is very easy to hook up. no problems at all.

The only minor con I have is that it only displays a few characters on the head unit.
Unlike mp3 players where you can read the artist, song and even album info.

Overall, this is a great product and I am vey please with it.
I'm sure I will enjoy it for quite some time.

Pioneer CD-UB100 USB Adapter

Crutchfield Customer Review (What's this?)

This is a Great product, Only wath you can expect from Pioneer
Very easy to install, Plug and play installation, just connnect the power and the IP bus conector to the back of the head unit and is that easy.
It can be used with any pioneer head unit as long it has the square blue conector in the back, it doesen't matter if is a very old or new head unit, it will work.
I use it with my Ipod also, and several other USB devices and it work perfectly it's fully compatible.
I't's a great choice for a non expensive upgrade to your sound system, and if you change your head unit for an other pioneer, just make shure it has the IP bus connector and you are good to go.
I'm very satisfied and I higly recomend the USB Adapter to everyone.
If you don't have it, Buy one NOW!! The Crutchfield tem wil help you to install it..

No more CD's

Written By Phil, Newport, VT on Monday, February 02, 2009

Crutchfield Customer Review (What's this?)

I was looking for a way to use a USB connection for my external hard drive with my Pioneer deck without buying a new one. I found this adaptor that uses the iP bus on the back of the deck. It was easy to hook up and works fairly well. You have to make sure the external drive you uses at least FAT 32 file system. The only complaint is that it takes about 30 to 40 seconds to read the files on initial start-up, but the convience of not needing any cd's in my car out-weighs that. It's a great buy if you dont want to upgrade your deck!

Pioneer CD-UB100 USB Adapter

Written By Nick, Portland, OR on Wednesday, October 15, 2008

Crutchfield Customer Review (What's this?)


It plays MP3's off of flash drives and hard drives, that's it.


If you were expecting it to have the same look as when playing an MP3 disc, you are mistaken (as I was). I have a DEH-P7800MP that has an awesome OEL display with a 2x32 character scrolling display. I would think that this would be something to be taken advantage of when creating a product like this, but it is not. All I get is an 8 character, non-scrolling display... pretty worthless. I'll be keeping the unit because it is my only option for the moment, but I am sadly disappointed in the overall look of the product. It shouldn't be that difficult to make it act exactly like an MP3 disc... all of the functionality is already there.

This is it

Great Product

Written By david, Minnesota on Sunday, February 24, 2008

Crutchfield Customer Review (What's this?)

This is a great product that does what it is supposed to do! Hooked this up and everything works on the first try! I am using a 2.5" laptop hard drive with an IDE to USB adapter and it works great! There is a second or two delay when switching between certain mp3s, though. The manual said there may be a delay when starting playback of audio files encoded with image data, and I know I have some files that are like that, so I'm going to get rid of that image data and try it again.

One thing that is left out in the description here is that the USB device you are hooking up MUST be Mass Storage Class compliant to work. This is most likely why other reviewers are having problems with their mp3 players. In other words, when you hook up your mp3 player to your computer to transfer files, it should show up similar to a USB drive, you shouldn't need any special software or drivers. If your mp3 player did require you to install such stuff, then I can almost guarantee you will have problems with this adapter.

Anywho, back to this. It supports up to 15,000 files, in up to 500 folders, on up to 250 GB. It, however must be formatted in FAT, which most USB devices are anyway, so that shouldn't be a problem. Has a pass-through IP-Bus so you can also hook up another IP-bus unit. I had a CD-RB10 on my old Pioneer and can still use it as an auxillary input on this! All in all, I am very happy with this product and would highly recommend this.

MP3 adapter

Written By nathan, Machesney Park, IL on Friday, January 18, 2008

Crutchfield Customer Review (What's this?)

I purchased this adapted with the understanding that I would be able to use my MP3 player to play on the radio. After installing this unit I have had problems with it working correclty. Customer Support sent me another unit to try to fix my problem, but I got the same results. It does not read the MP3 player, it will hook up to a hard drive but does not show play list on the display making it pretty useless. I am now using the USB port to run my hard drive after trying three hard drives I contacted Tech Support again and they told me exactly which hard drive was used in making the instruction video on your website. Finally it works, but I am not able to return the CD-UB100 because in order to remove this unit from my truck I would need to remove my seats, dash, carpet, etc. So I have decided to keep it and maybe find a use for it someday; in the meantime it is in my truck uselessly!!!

Good idea, not compatible for all

Written By Peter, Rochester, NY on Tuesday, June 05, 2007

Crutchfield Customer Review (What's this?)

NOT recommended for DEH-P9800BT; appears incompatible with pre-5G/Nano iPods.

I bought this unit with very little detailed information about head-unit/iPod compatibility and how it differs from the CD-IB100II (see my review). I was hoping the UB100 would overcome some of the IB100II deficiencies.

Problem 1) Deal breaker - It would not play from my 4G iPod (also does not work with 2G Shuffle - not expected, but worth a try; 5G/Nano may be fine).

Problem 2) Minor inconvenience - The UB100 is newer than the 9800BT, so it is recognized but shows up as 'EXT' (rather than 'USB') and has some minor control limitations.

Problem 3) Trivial - I couldn't get it to play at all from a USB flash drive (3 songs on it: 1 each MP3, AAC, iTunes Protected AAC), although I didn't spend much time troubleshooting the flash drive issue since my main requirement is iPod connectivity.

Rating: 3-stars as an attempt to be 'neutral' - I can't enter a review without a rating and I don't want to skew the average too much. I am not surprised that it didn't work for my application (I almost expected it wouldn't) but I am slightly disappointed as the 9800BT is still considered the flagship model in its line and only iPods released after late 2005 seem to be compatible. This is likely a great product when paired with the right equipment (just not mine).

Kudos to Crutchfield - they waived S&H, and, as always, a hassle-free return process.

Great Add on

Written By Pat, Upper Darby, PA on Friday, February 16, 2007

This is a great add on for those who have a lot of music. I connected a 60 gig portable hard drive with about 5,000 songs. Depending on the head unit you are using, (I have the DEH-P860MP) you are limited in functionality. But for the most part you can track forward, backward, pause and have random. You can elect to have the song or artist or folder name in view. If you take the time to organize your music into proper folders, you can easily navigate through your music. The one downside is if you wish to have the song title scroll through the unit's face, you have to do select the feature with every song,the Ever Scroll feature does not work. It's nice have everything in one spot and really no need for time consuming MP3 cds. One upside is there is an extra Bus port on the unit to allow for a pass through of a cd changer or AUX input. In my case, my Sirius tuner. Enjoy.
