Sadly, the bluetooth connection through the Viseeo tune2air would not allow me to connect the iPhone 6 to the sound system in my Aston. It has exactly the same problem as when I plug the phone in using the 30 pin cable with a 30pin to lightning adapter -- the car systems simply says "iPod Unreadable".
The iPhone 6 itself will not play any music when connected to the car (whether connected by cable or, I have now discovered, by bluetooth using the tune2air). If if press play on the iPhone 6 when it is connected to the car it just jumps straight back to pause. If I unplug the phone or switch off the bluetooth connection, the iPhone plays music itself without problem.
Clearly, iOS8 and the Premium Sound System in the Aston are just totally incompatible. A great shame given that iOS7 and before worked perfectly with the system in the Aston. iOS8 just says no to all functionality when connected to the car.
There is no message on the phone itself when I connect it to the car, only a message on the screen in the car. The iPhone just won't play when connected to the car as said ahove -- it will just jump straight back to pause if I press play on any track when connected to the car.
The only connection that works in the analogue connection using the hedphone socket on the phone and the 3.7m aux-in on the car. Sound is not as sharp or clear as a digital signal, so some detail is lost, and the volume needs to be cranked all the way up on the phone to generate a strong enough signal to get a reasonable level of volume out of the car without cranking the volume on the car all the up. No ability to control the phone through the system though when connected this way, so this is clearly a less than ideal work around by some considerable margin.
I wish it just worked. Surely it couldn't have been that hard to make it work. Every version of iOS worked up until now. This latest one just doesn't work.
I tested the Viseeo tune2air on an old iPod dock I have in the house just to rule out any compatibility issues/functional issues with the Viseeo itself. That connects fine to the iPhone 6 and allow music to be played from the music app and streaming via spotify or google play music through the Viseeo. The Viseeo also allows my old iPhone 4 to connect to the car using bluetooth with full functionality. Oh well. Think I might just return the iPhone 6 before my 14 day return window expires and stop obesessing about this until Apple/Aston can get their act together (and assuming I don't buy a Sony Experia in the meantime).
