Hi Neil,

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

Cheers,

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

Cheers
