Downgrade to BT 3.24 .. where to find file

Good morning,

This is an older topic regarding losing bluetooth connectivity to Pioneer's avic series when upgrading to 3.3 from 3.24. Years ago I had downgraded back to 3.24 and resolved issues i was having connecting to the head unit.

  Recently my radio crashed and I found someone on ebay who fixed it.... he did an amazing job.  However, he upgraded the BT back to 3.3 and the "fun" trying to connect is an issue again.  Would anyone have a copy of the 2012 BT firmware and/or the cnsd-310-fm they wouldn't mind sharing?  I have spent a couple of days searching the web with no luck.

Thank you in advance!
Dave

If you searched AVIC411 you'd find at least one link to download the files. See this thread.

This firmware should work with most Z and X series.
