If you have the Echo 2nd Generation, you will not need to use the adapter. The adapter is used to insert the Echo Input.
- Separate the two-piece Echo Input adapter, then place the Echo Input between the top and bottom adapters, leaving the USB port accessible on the back.
- Close the adapter, then insert into the iAV5v2 dock so that the USB port is exposed on the back of the unit.
- Gently push into place.
You may view the setup videos in the "How to Videos" section below for a full demonstration.
