Suggestion

You shouldn't need new software to get them to run together but the 7860s do have the reputation of being a bit flakey.

Coverage and how to read this overview

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

3 eligible posts · 0 unverified posts · 1 discussions match the subject in their title or opening post.

POST 1 / ORIGINAL POSTEROriginal post

I have recently purchased the 7860 cd changer for my 1999 911 as the previous owner had removed the changer when selling. I have plugged the unit in and you can hear the motor start but the stereo is not recognising the cd unit is there?? Do i need some software or something to add to the cdr22 stereo??

POST 2Original post

I assume you connected the two with a cable like this? http://cgi.ebay.co.uk/Becker-CD-WECHSLERKABEL-Kabel-NEU-5-5m_W0QQitemZ170095199481QQcategoryZ14259QQssPageNameZWDVWQQrdZ1QQcmdZViewItem Blue and green in the back of the CDR22 and the red/white/black connectors to the 7860? Have you cycled through the S button to see if the CDC is recognised? (You should get FM/CD/CDC in that order, do it a couple of times. If you do get CDC but no sound then check the discs are the correct way round -- check the Cd carosel. You shouldn't need new software to get them to run together but the 7860s do have the reputation of being a bit flakey. Good luck.

POST 3 / ORIGINAL POSTEROriginal post

Thanks Paul, Not sure how !- but the unit has now recognised the stereo and is working. I may have had a loose connection, thanks for the advice. James
