2005 Honda Odyssey with a 6-disc CD changer, AM, FM, and Aux functions on the stereo. Need Bluetooth Adapter?

I have a 2005 Honda Odyssey with a 6-disc CD changer, AM, FM, and Aux functions on the stereo. I need a bluetooth adapter to connect my phone/Mp3 player. All the adapters I have seen require a device to plug into the CD Changer port of the stereo, however I do not want to lose my CD player. Is there a device that will utilize the Aux function, that the only available port for is in the back of the van and therefore not used, to enable bluetooth to the stereo?

Plug one of these into your aux port: https://www.walmart.com/...er&veh=sem
