Managed to get my ipod playing. Iphone is still not working. Comes up with the yellow triangle with the exclamation mark in the middle.
Now the ipods working i'll just use that an keep updating it. Cheers for your help guys. Much appreciated.
You can ignore the warning message. It simple highlights, albeit generally, that the connected device isn't compatible. This can be for various reasons. For example, in this case, it has detected that there is no power supplied by the connected device. It'll still be able to route sound through the car.
One of three things is most likely causing your issue...
1. Your phone's connector is clogged with gunk and is either...
a. Causing poor connectivity on the pins or
b. is so clogged that the male connector in the dock doesn't even fit in the female connector of the phone
2. Your phone isn't secure in the dock because of the lack/poor design of the Audi cradle for that device model
3. The male connector in the dock has become damaged. This is often caused by users either leaving a heavy device connected without a cradle thus, placing excessive leverage on the connector, pulling it down and breaking pins.
Just buy a 30-pin iPod extension lead from eBay. £4ish is worth it.
