Sony CDX757MX MP3 10-DISC CD Changer

It’s Sony and it is designed the way Sony designs things. They were the first to identify the need for a cd changer that held TEN cds. It functions with almost all Sony head units.

This product received good reviews, but it would not work with my 2007 Toyota. Seems more car markers have proprietary radios that don’t allow add-on disc players. Before you order, do some research to determine if you can use this item in your newer car.

This is the second cdx-757mx that i’ve owned. The last one was several years ago, and I went with a different brand due to some problems. The newer 757’s are greatly improved over the ones from a few years past. Sound quality is very good. It still doesn’t like Variable Bitrate (VBR) MP3’s, or ID3v2 tags, but both problems are less prevalent than before. It will play 192VBR files (“alt-preset-standart” is what I was using) but has occasional glitches due to the bitrate shifts. I’m currently playing 224CBR files and it does not glitch at all, and sounds extremely clear. I’m running this with the old school Sony ES stuff (cdx-c90 + xdp-210eq) powerful amps and good speakers (Dynaudio, DLS, Seas). With the old (pre-MP3) unilink headunit, I cannot see the MP3 tags; but it does show the file name (ISO 9660 level 2 gives you 31 characters for the filename, which the unit seems able to show). There is one problem when displaying the folder name: with the old headunit it incorrectly shows the first folder on the disk, instead of the folder the current song is in.
(Note: ID3v2 tags are the unlimited-length ones that live at the front of the MP3 file, as opposed to the standard ID3v1 tags that reside in the last 128 bytes of the file). If you remove the v2 tags, the unit will play the MP3 files just like CD tracks; if you have v2 tags, it pauses before it plays the track while it searches for the start of the music.
All-in-all I think this is a very good player, with a fine (but not perfect) MP3 codec. Currently it’s the choice if you have a unilink headunit.

owned in USA, then came in luggage to Europe (here in eu this would cost 2x more). So using more than for a month now and its plays nice, good time for disc change, great sound quality, plays all my discs, no skipping at all, even on dirt roads
easy to install and mount. Very recommended.

I mounted this system in a locker below deck on my boat, and let me tell you, with all of the pounding and rough conditions often encountered out on the water, this thing plays without skipping.
The anti-vibration mechanism has to be good, and I am sure that a boat will put it through much more rough treatment than your local potholes.
