Extremely annoying Bluetooth A2DP drop-outs
Hi
I have a Kenwood DDX-8024BT headunit in my car
My iPhone 4 is running iOS 4.3.5, and is not jailbroken. It's also out of warranty.
The headunit and phone have paired OK, and I can make and recieve phone calls via the headunit.
The issue is when I try and stream audio from the phone to the headunit via A2DP. Everything starts fine, but then after a random length of time (it varies - some time it's seconds or so, others minutes), there is a momentary loss of audio. Then it comes back, and is ok again for another random period of time. This continues for as long I'm streaming audio. I sometimes get several dropouts in rapid succsession, othertimes it's ok for several songs. It's very annoying! 😠
The iPhone streams music fine to my bluetooth bike intercom. No drop outs whatsoever.
I've tried the following:
Updating the BT software on the headunit (It did exactly the same on the old version as it now does on the new)
Updating iOS as soon as there's a new version, in the hope that it might have some effect.
Deleting the BT profiles on both the phone and the headunit, and repairing them after the S/W update
Killing all other background apps on the iPhone that maybe still running in the background
Reseting the network settings on the phone
Turned off 'Ask to join networks'
Rebooting both devices (many times!)
Sending the Headunit back to Kenwood for repair (replacement Bluetooth module)
None of them have had any effect - I don't believe it's ever worked properly, on any combination of headunit firmware / iOS
So - is there anything else I can try? Replacing the headunit isn't really an option... And I have exhausted the different settings on the headunit. Anything I can do in the settings on the iPhone?
Cheers
Jason.
