Sony CDX changer problem reading mp3s.
 

I've just had a Sony CDX-T70MX changer installed in an Audi A6, with an
adaptor to make it compatible with the Audi Concert head unit. When playing
mp3 files that I've burned to a CD, I find that the changer will play the
mp3 files OK, but if I try to skip to the next track or go back to another
one, it just goes back to the first mp3 in the list and starts again. It
doesn't seem to recognise folders, either - just plays the mp3s on the discs
that are not in folders.

Is this something just have to put up with? I know these things happen with
mp3 players, but I was wondering if it has anything to do with the method I
use to burn the CDs (Roxio Easy CD creator). Any tips or advice
appreciated.

After some communication with Connects 2 (who were knowledgeable and
helpful), Sony and the fitting company (more about them later) we found
out
that early models of this changer DID NOT work correctly with the Connects
2
convertor. In fact, only models after a certain serial number were
compatible and offered full track skipping functionality.

Found my old emails from Connects 2...

They originally told me (way back in July 2002 or thereabouts) that units
with a serial number below 16955 when paired with some connects 2 adapters
were prone to displaying the problems described in your original post.

BTW - After finally getting mine sorted out it has worked well for
45000miles worth of listening...(although searching this group will tell you
that there are some limitations to MP3 quality that should be remembered
when ripping/encoding... e.g. CBR at 256kbps and below is about maximum
quality the unit can handle and avoid using VBR... most people seem to use
192kbps CBR)

Many thanks, Dave. So the problem can be overcome - excellent news. The
changer was installed by Halfords, who tell me they used a Sound On Top
interface, which turns out to be a partnership venture between Connects 2
and Sony. They have a website at www.soundontop.co.uk Sony are looking
into my problem and are getting back to me............

From my experience....

After the first install I found that the changer would NOT skip backwards
or
forwards through the tracks... rather, it would return to the first track
whenever track skip was pressed. As you can imagine this is quite
frustrating when you're on track 78 and you want to skip to 80 and all the
machine does is return you to 01. A different unit was installed and I had
the same problem.

out

compatible and offered full track skipping functionality. On the third
attempt I got one of these fitted and everything has worked since then.

Is your adapter a Connects 2... you may be suffering from the same
problems
I had with my first 2 changers...

Should have nothing to do with burn method as long as they are burned as
data although some people recommend that the disc is finalised after
burning... I've not experienced any issues with not finalising discs but
there you go

Good luck

Hi Neil,

Yes, I've phoned Sony and also e-mailed Soundontop for good measure.

Cheers,

Hi Ross,

Have you contacted Sony or the Soundontop helpline?

Hi Ross,

The problem occurs because the Audi head unit wants to know the number
of tracks on the disc. We get this information from the TOC info on
the Sony changer. On an MP3 ISO disk the TOC contains the number of
sessions on the disc, hence if you have written 50 MP3 files in one go
( session ) the adapter reports only one track to the head unit and
track 1 is always selected.
Sony added some new commands into their latest T70MX software for me
which reports the number of playable MP3 files.
For the MP3 changer to operate correctly in your car the T70MX needs
to have the newer firmware and the adapter needs to be the MP3 version
not the normal CD version.

The first batch of changers manufactured with the incompatible
software have serial numbers up to 19655. I believe that some of the
first batch of changers have been re-programmed with the newer
firmware, but I have not been given any information on how to identify
which ones.

I hope this information will help you when you go back to Halfords.

TTFN

Neil

Hope you get things sorted out...

Let us know what response you get from Sony... all I got was a "We're aware
of an issue and are investigating it" which was a year ago
