Iphone 4s Bluetooth problems after upgrading to IOS 6.0

I have an iPhone4 and a Pioneer AVH-P2400BT car unit. I've upgraded to IOS 6. The update (from what I've tried and what I can tell) is NOT reversible.

Here's what I've found happening between the iPhone & Pioneer for bluetooth streaming audio:

1. The track/artist info no longer displays.

2. The track skip buttons no longer function.

3. The pause/play button no longer functions. It may SEEM like it does, but it simply mutes the audio, the content continues to play (silently) on the iPhone.

4. The content no longer resumes when the vehicle is started.

5. The content will pause when the vehicle is turned off, but a couple of seconds continue (silently) on the iPhone.

6. If content is paused by the vehicle being turned off, it will resume playing on the iPhone speakers following an incoming phone call, whether answered or not. (This can be a little embarrassing, depending on the content of your prefferred podcasts! 😊 )

I tested this with other devices i have that will control the music via bluetooth and confirmed that it is Alpines problem, not iOS. I called Alpine and they said that there is a known compatibility issue with iOS 6 and they are working on a firmware patch for the units. Don't give up on either the phone or the stereo because of this setback, they are working to fix it and your unit can be patched just like any other device. Call alpine and confirm if you want, but take it from this software engineer, its not iOS thats the problem.

Edit - It may be a compatability issue with using the new bluetooth protocols. I'm sure its not all iOS's fault, it may very well be partly due to the stereo manufactures.

I have an iPhone4 and an Alpine CDE-133BT car unit. I've upgraded to IOS 6. my iPhone to iOS 6 and I'm experiencing some problems pairing the iPhone to the car unit for bluetooth streaming audio, for exmple the track/artist info no longer displays.the track skip buttons no longer function, the pause/play button no longer functions and so on.

We have to wait for for ab iOS fix or what can we do?

Please let me know

I have issues with Bluetooth too I can't even use the Bluetooth in my car because it won't stay connected and I have a factory stereo in my 07 Acura tl it's really ******* me off they need to fix the ios6 because its not my stereo

Just want to add my name to the rollcall of unhappy iOS6 and Alpine users. Things worked so well before the update. Apple, please fix!

I contacted Pioneer tech support and this was their response:

"Our engineers are currently working with Apple to see if there is something we can do to restore the control and metadata from the Bluetooth Audio streaming."

I hope a fix is released soon!

I heard today Alpine. They said that soon will release a fw update for ios6. 😉

Similiar problem here. Does connects to my Mazda 2010 stock radio fine at times, but most of the time I have to turn bluetooth on and off then on again when trying to make a call over it...

We Hope in Alpine !!

Apple wake up ! it's a big problem. I have the same problems with my Alpine 133BT car unit.

I've got an Alpine CDE-W235BT and really loved it. I have an Iphone 4S. Before the IOS6 update it was working perfectly with bluetooth, metadata, skip/play/pause/ Track info, all working from the head unit.... post IOS6, I no longer have control of skip/play/pause from the head unit, and no track info.

It still streams music but no control or track info, I have to unlock the phone to skip a track rather than press one button on the stereo wihtout taking my eyes off the road.

Is there an update we can download to fix this problem?

I just bought and installed this CDE-W235BT less than 2 months ago.

It's not only your hardware, I have hearing aids because I'm rather deaf. These connected to my iPhone with no problem but now if I disconnect it takes forever to reconnect when actually they should be a trusted device and oink straight away

I gather Apple refuse to change which, bearing in mind the number of issues, is a bit arrogant and very sad

I have the same issue with my Sony DSX310BTX. Before the upgrade, everything was working perfectly. Now, i when called someone, i can hear the person but it don't hear me. When i listen my music via Bluetooth, the music cutoff evry 5 sec.

I have the iPhone 4s (iOS6) and Alpine CD-HD138BT. I am experiencing the same problem, obviously. I called Alpine today to follow up. They said it IS iOS6 and not Alpine's hardware/software causing the problem. Sadly, he also said "we don't know what to tell you." He said it's being looked into, but didn't seem to know if a firmware update would fix it. He didn't offer much hope. I asked if I could return it to switch it out with another unit, to which he said no b/c it's not their equipment that is to blame. However, 90% of the reason I bought it was for that funtionality - which no longer works properly. They don't seem to be too eager to let their customer base know they are looking in to this issue and and ETA as to when that could happen. Why can't they post something on their website concerning it?

After upgrading to IOS 6.0.1 remening the same problems witj Alpine... Bad story Apple.
