Can you tell me how this works on a practical level.
The ipod is in the glove box, for example, and its permanently connected to the 6 cd changer via the Denison Gateway.
1. You turn on the ignition, does the music start straight away, or do you have to get the ipod out and turn it on, select album, etc.
I've got mine set up with the ash tray dock mod, see below. I dock iPod and press "cd" on the headunit, music plays instantly.
2. Can you control the volume using the standard volume knob on the symphony. Normally if you press the volume knob in, it turns the music off.
Does this feature work with the ipod.
Yes, press it and headunit turns off and stops charging iPod. Volume works as normal too.
3. When you turn the ignition off, does the ipod stop.
If you turn ignition off it'll continue playing until the key is taken out of the ignition barrel.
I have just bought a 6th generation nano (yes the very small one) and am looking into getting it installed into my 2005 A3 sport. I have a feeling you might get different results with different installations.
