changer works very well, sound quality is excellent, and no problems with bumpy roads. the only issues i have are in the mounting and installing new cds. i removed an older sony cd changer and found that the mounting pattern is completely different. standardized patterns or an adapter plate would be nice. i had to make wooden spacer blocks and install between the panel and body. also the cd holders are very flimsy and awkward to use. a minor point, the holders are not numbered and the play sequence is back to front. i would recomend this unit to be used with a sony deck. the xplode technology does make a difference.

I bought this to go with my MEX-BT3700U head unit and it works great. Hung it from the front seat springs as the cab of my truck is quite limited. If you need a unit that works with any head unit (FM modulation) this is not it as it is designed to work with Sony head units, so do your research and you won't end up like the moron in the other review. I make compilation CDs of several albums converted to MP3 and recorded onto one disc. I have 6 Yes albums on 1 CD, 5 Kansas, 7 Genesis, etc. and this allows me to carry a ton of music in the car on just a few discs. I wish it played .wav files like the head unit, but I'm more than satisfied with it.

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.

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.

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.
