My iphone 4 worked fine with my Alpine stereo in my Porsche. The artist, song, and album showed on the stereo display, and I could pause and skip through the radio controls. Most of that stopped working when I updated to an iphone 5. Data no longer displays, and the radio control over the iphone has been lost.
According to the stereo installer, other stereo brands are also affected, and Alpine is supposed to be working on a firmware fix. I hope it's soon.
Same issue here with the newest Kenwood BT-Receiver.
After having spoken to Kenwood about these issues I got into a discussion with the quite knowledgable call center agent about how Nokia intended to re-define the Bluetooth-Standard back in the day and how this failed attempt put the massive dent into Nokias (then) very convinced and utmost loyal user-base.
Very sad to see the similarities in these two cases and getting ever more disappointed in Apple.
Obviously, Apple is also neglecting the numerous requests by car-stereo manufacturers to sit at a table and speak with them about how to solve this very wide spread issue.
So... another one. I have a built in BOSE System, that was really something you love while driving, and with my 3GS it was indeed lovely. Yesterday I got my Iphone 5 and... well.. no more concert feeling, since I can not connect via bluetooth, as all the other guys described here. The connection works at least via the built in USB port, I can play the songs and so, but the control via car screen is not possible, and as someone mentioned before, it might be risky on the highway if you tap on the phone while driving.
But... why do we post all this here, when no one from Apple is going to answer? Or will they?
Not sure if people are still having this problem, but I happened across a solution yesterday by accident.
I have an iPhone 4S and did the update. Streaming music via Bluetooth in my car was a lot more spotty and sound quality did go down. One day the song information stopped appearing on the car unit screen and I was no longer able to control music on my iPhone with my steering wheel controls. I could adjust the volume, but nothing else.
I recently got some headphones for Christmas. Similar issue. The headphone controls worked only for adjusting the volume. I could not pause, play or skip tracks with the headphone controls. I found the following solution in another Apple Support Community blog:
Plug in headphones. Go to Settings>Music>Volume Limit. Slide the volume limit down then slide it all the way back up. Then restart phone.
My headphone controls worked after I did this. Surprisingly, when I got in my car the next day, everything was back to working order. All steering wheel controls worked and song information was displayed.
Seems the issue with the car controls and headphone controls are somehow related. Anyway, give this a try if you are still having problems. It worked for me.
Pioneer has posted a firmware fix for many of its car stereo receivers. Thank You Pioneer!
This post may or may not help some of those with Bluetooth problems on a Pioneer Head unit...
I have never had a problem with Bluetooth on my Z140BH. Everything has worked as it should beginning with iOS 5.x on an iPhone 4S and continuing to 6.0.x on an iPhone 5. No problems at all.
When I updated my iPhone 5 to iOS 6.1, however, that all changed. Nothing worked correctly via Bluetooth. The handsfree wouldn't even pair and the audio portion worked--sometimes--but was really unstable. Neither of these symptoms had ever happened to me prior to the update to iOS 6.1.
I tried everything I could think of to get the Bluetooth to work, hard resetting the iPhone, 'forgetting' and re-discovering the connection on the iPhone, changing the profile on the Z140BH, etc., but I had no success until I bit the bullet and did a factory reset on my Z140BH. After the factory reset everything worked as it should--again without any problems at all.
My guess is that somewhere along the line the Z140BH Bluetooth setup became corrupted and the factory reset cleared it out. I did have to spend a few minutes setting up my head unit again, but that was a small price to pay for having the Bluetooth work properly again.
Hmm...have to put my 2 cents in here! I have a 2012 Audi A7, full Bose setup, etc. and a 64 GB iPhone 5 with all the issues as described in various ways above. My Music does stream beautifully..always...it's just the d*** display with the Artist, Song, Title info. Just upgraded to IOS 6.1.3 and thanks, Salem, a hard reset does work wonders. The Audi has copied my whole contact list so the dislpay always shows who's calling, their number, etc. and the dislpay shows two rectangular buttons for answer and end call. I'm saying this because the Artist, Song, Title info always comes back after I answer and end a call this way!! ??? No clue why.
Gotta love those Germans! The Bluetooth & Wireless internal modems will reset themselves by....opening the driver door for ten minutes, then closing it__little switch in there somewhere. Geez! Soo, some of the time I can get both the Music and the Display working at the same time. The other day, my Audi lost its Bluetooth connection and the display showed it was resetting itself. Afterwards--guess what?-- Display and Music started working again and for the whole day!
The bad news for the Audi is---Bluetooth and Wireless are handled by T-Mobile ( Oh No! ) Talked with T-mobile at length -- several departments -- and basically they said that the iPhone 5 is too new a phone and their software has not been updated for it yet! [And they don't know when ] ( But it is 100% compatible with the iPhone 4 )
Guess that's 10 cents worth :-)
I had the same problem with an Alpine deck. I tried a couple of the suggestions in this thread, but they did not help. I eventually found my answer here:
My deck supported the AVRCP 1.3 profile for remote-control of audio playback, but iOS 6 uses the 1.4 profile. I was able to upgrade the Bluetooth firmware based on information I found here:
After the upgrade, song titles were back, and I could once again control playback from the deck.
Hope this helps.
I had the same experience. I went to the alpine website and downloaded the firmware update and followed the instructions.
The Alpine instructions are detailed and easy to follow, and problem solved.
The download is hard to find, click on the support tab and then click on find an owner's manual(???) and type in your model number. You'll get several links back one will be for the firmware download.
This will require a laptop that you can take to the car.
