Mp3 is a type of encoding, it has nothing to do with speed. If your
factory unit is not an mp3 unit then it cannot play mp3 encoded discs
(and if the unit plays mp3, it will say so in the manual). The rate of
encoding means nothing when you play it back, it only means that the
disc was "written" at that speed (which translates into how much time it
took to write the disc).

Look I REALLY appreciate the reply but, it's painfully obvious that you
don't know in the least what the f.ck you are talking about.
Let me start by explaining to you a bit about myself. I'm a 49 yr old IT
consultant/network engineer who owns a thriving business. I eat, drink,
sleep, breath, sh.t, piss, fart, walk and talk computer technology. Ive
been encoding MP3 audio since certainly before you knew what the f.ck it
was and for all that, before most anyone knew what an MP3 was. If you
understood the technology, you would have known that certain playback
devices have a criteria to meet regarding how the MP3 was encoded
and the named. It's been my experience with stand alone
players that some require the MP3 to be encoded at a specific bitrate(not
variable) and use an 8.3 naming convention format or the f.cker just won't
play. The factory installed deck in my 03 Trailblazer will load the disc,
show the tracks, looks like it's playing (time counter) , but not produce
any audio which again from experience tells me the deck is looking for a
certain encoded bitrate. I have a Sony stand alone CD player that does MP3
audio but only if the MP3's are encoded to 128kbps fixed. Anything other
than that and you will hear nothing.
I guess what I need to do is to try to consult the manufacturer or just
burn some MP3's on a CD at different bitrates and see if any will play.
And there is always the possibility that this f.cker just doesn't play MP3
audio even though it can physically plays the file. Maybe it doesn't have
a decoder built in, maybe it was an option, who the f.ck knows. That's why
I posted the message here thinking someone may have asked the same
question.
Have a GREAT day !

Sorry friend,
A compressed audio format that is popular for downloading across the
internet and for use with memory-based audio players. Files may be recorded
on CD-R or CD-RW media for playback in compatible DVD players, audio CD
players, and CD-ROM drives. Files are usually named as "*.mp3". Sound
quality varies as a function of the recording/encoding bit rate. In our
opinion, anything recorded with less than 128 kbps data rate will sound
degraded.
The recording bit rate ( or in the music world sampleing rate) has to do
with the way the sound is compressed and played back. with a rate of 128
the player must convert the digital information back into analog for the
sound to be sent to the speaker. Many players have the ability to convert
all of the standard rates, some do not.
You may want to check you facts before you open your mouth and make yourself
look like a fool.....
What may be going on is that the player is trying to "play" the Mp3 as a cda
(cd audio, the native format for commerical CD'S). This I have seen happen
more than once..........
if this is the case you can add a rf modulated cd/mp3 player or a Mp3 player
harddrive system to your current system....

I have an XM unit with a behind the dash RF modulator but I was really
hoping the stock deck had the unadvertised ability to decode MP3 since it
didn't just spit the disc but rather showed it was playing tracks. I have
seen others require a specific recorded bit rate that would play the track
but not be able to decode the audio. I still haven't tried other rates
besides what I thought might be fairly standard at a fixed rate of 128.
However it may just be the fact that it will not play MP3 even though the
same deck in newer models did.
