So I just bought a Sony xplode CDX-GT620 U. It is a nice unit (nothing fancy) but it does the job just fine. it has a usb port which i love, and it looks cool in the dash....everything works fine except....

I cannot MP3 cds to work. am i missing something? the unit can read mp3 as it advertises, and it does read them through the usb port. but once i insert an mp3 CD (basiclly, i copy mp3 files to a cd), it will not read , and give me some error about unsoperted media or soemthing like that.....

what am i doing wrong?

any help will be much appreciated .......

thanks...

you cannot just copy the files to the cd.
The files are then data images that the h/u doesnt recognize.
You have to burn the cd as an mp3 cd.

Explain this further please if you can ....

if i burn mp3 files into an audio cd as an audio cd, you will basically end up with a low quality audio cd. I thought the whole idea of creating an mp3 cd was to utilize the small file size therefore have more music on one cd.

am i correct on this?

thanks,

It should recognize MP3s on a CD if the disc is burned as a data disc. Unless the Sony is different from the stock Chrysler units.

thats exactly what i was thinking. it reads my flash drive perfectly even as regular MP3 files, so why can't it read a data CD with mp3 files on it....???

anyone with sony's have any idea about this?

Danteneon, since when do chrysler's cd players read MP3? never new that....maybe the newer units?

thanks,

Yeah, the newer ones do, like the stock HU in my wife's Caliber. 6 disc changer with 120 tracks each FTW!

If it did not read them from the disc,
it is because you burned the disc with DATA FILES not music files.
You have an option in nero express (idk what software your using)
to burn an mp3 audio cd, this STILL enabled you to add 100 songs to a cd.

Whoops, my bad. I should have said MP3 music disc, not data

i'm pretty sure that he's not a complete tard and knows that if hes trying to get mp3s on a disc hes going to use mp3 files and not "DATA FILES" as you suggest. i think you are off topic on this matter.

"you cannot just copy the files to the cd."

incorrect, it IS as simple as that.

i also dont know what burning program you use, but it really doesnt matter anyways... in nero for example youd use CD-ROM (ISO) as the type of disc.. and thats a standard in any burning program... and then you throw the mp3 files into it. then burn it. and then youre done.

theres no difference in burning an mp3 cd or a data cd.. they are the same thing.. the mp3 files are still data files and they are still mp3 files.

make sure the mp3s you are using do not have DRM (from itunes, etc) since the player will not play protected files... other than that you might just have a bum player... in the past ive had various problems with sony players..

and make sure you are doing everything with these guidelines in mind (from the user manual)

Notes on CD-R/CD-RW discs
• Some CD-Rs/CD-RWs (depending on the
equipment used for its recording or the condition
of the disc) may not play on this unit.
• You cannot play a CD-R/a CD-RW that is not
finalized.
• The unit is compatible with the ISO 9660 level 1/
level 2 format, Joliet/Romeo in the expansion
format, and Multi Session.
• The maximum number of:
– folders (albums): 150 (including root and empty
folders).
– files (tracks) and folders contained in a disc: 300
(if a folder/file names contain many characters,
this number may become less than 300).
– displayable characters for a folder/file name is
32 (Joliet), or 64 (Romeo).
• When the disc is recorded in Multi Session, only
the first track of the first session format is
recognized and played (any other format is
skipped). The priority of the format is CD-DA and
MP3/WMA/AAC.
–When the first track is a CD-DA, only CD-DA of
the first session is played.
–When the first track is not a CD-DA, the MP3/
WMA/AAC session is played. If the disc has no
data in any of these formats, “NO MUSIC” is
displayed.

Once you copy an mp3 to a CD, it should work regardless of the software. that is how the Head unit reads it off the USB drive anyways...

I think my software is creating a multi session cd, instead of finalizing it... that is probably what is going on....

i will try it and see ....thanks everyone for the input.....

Fixed it ...

it was the issue of finalizing the CD, Thanks jT for bringing my attention to this...

Glad to hear thats all it was. Enjoy hours of music at a time sir

my issue was with the older h/u's that first supported mp3 playback u could NOT just drag and drop the files. no one else was helping him so i figured id blurt that out easy guys.
