Here is one idea to try. (I have the Amazon Echo, but not a CS+.)
Use a PC (or Mac) connected to the same WiFi as your Tap.
Then navigate to this webpage on the Amazon site:
http://alexa.amazon.com/spa/index.html#settings
Click on the name of your Tap.
Click on Bluetooth
Click on the [Pairing Mode] command button.
Then try to connect with your CS+.
And, here is a link to the Amazon Help Page for Tap <-> Bluetooth
