When I upgraded my iPhone 4 to iOS 5, blueooth connectivity with my Clarion FZ709 car stereo no longer works.  The phone and stereo will discover each other fine but when the phone connects it drops the connection after 2 seconds.  Attempting to reconnect has the same results.


Undiscovering and rediscovering doesn't work either.

    I actually submitted a bug for this months ago. I did communicate back and forth with apple and got it diagnosed. Unfortunately, they told me it was a known bug and closed my ticket as a duplicate. I'm not able to see the other bug to find out its progress which kind of *****. With each new beta I tried again only to see it still failing. Based off the Bluetooth codes I was seeing in the logs, it looks like the receiver sends some codes to the phone which were not understood, and for some reason it decides to disconnect instead of ignoring. Hopefully they'll fix this soon. Pretty annoying that you can't use the Bluetooth already in your car.

    You are not alone in this. I'm having the exact same problem with my Clarion FZ709. The main reason I bought the head unit was for how well the bluetooth phone and audio streaming worked. I hope they get this fixed soon.

    Count me in as another "me too".  Thank you for posting and keeping the thread updated with changes.  I will be keeping a close eye on this.


    Did Clarion give you any details on how this is going to be resolved?  My first guess is they are going to work with Apple to make sure the fix is in included in the next IOS update.  I can't imagine them issuing a hardware replacement, which seems like the only other solution due to no obvious way to update the receiver's firmware.



    Nathan's post clearly indicates this is something Apple knew about well before issuing the final IOS 5 update, which means they categorized it as not important enough to fix beforehand!  I understand with any new product or release there is a deadline for it, and there isn't always time to get everything working 100%.  The professional way to handle this would be to put a big red "warning" button next to the "update" button that users have to click on to update their device.  Clicking on this button would list all known bugs along with the proposed solution to each of them (i.e. will be fixed in next update or won't fix etc.).

    Same here, for me it's a big problem because I use my phone for work which means that I won't be able to receive calls through my car stereo

    I have this bluetooth connectivity problem as well. I cannot connect my iphone 4 and ipod touch 4 to my headset at the same time. It workes fine when I had a 3rd gen ipod touch.

    I also have the same problem in our VW Passat (Blaupunkt manufactured stereo). So it seems to be a fairly general bug? In my case it keeps connectivity as long as I'm playing music or having a phone call.

    Thanks again B. Kennedy for the info.  As soon as I get time, I will fax Clarion and downgrade my iPhone.

    That's all good and well if you have an iPhone 4

    But I have the 4S which you can't downgrade..

    Im glad I found this post, I was concerned I was the only person with this issue, Its annoying the **** out of me and im going to downgrade my OS purely because of this. I will be contacting clarion myself tomorrow and helpfully if we get enough people either clarion or apple will fix this.
