Does anyone have any ideas what I might be doing wrong? I bought (4) used Ipods (I'm going to return them of course) to test on my Avic D3 and all of them get the "Error 11" code, EXCEPT for my sister's Iphone 4 running iOS6. I have tested the following iPods:

 

2nd Gen Ipod Nano

3rd Gen Ipod Nano

1st Gen Ipod Touch

4th Gen Ipod Touch

 

NONE OF THEM WORK!

 

The only one working is the iPhone 4... and that's it. I don't know what's going on??
