I have a '06 Five Hundred. Has Aux button on radio but no place to plug one in. I would like to be able to have a connection to my phone as well as have hands free calling. I know there are FM transmitters but from what I have seen of them I have to change to that preset station every time I want to talk on the phone. Also, when I travel I may have to keep changing the FM station I use as I move into new areas. That sounds like a pita.
At the very least I need a good hands free Bluetooth connection for the phone.
Any suggestions?

 

Welcome to the site..

Look up ‘PIE’ Interface adapters.
They manufacture interface modules ‘Y’ cable plug’n play connectors that plug into the radio, and the cars harness plugs into the interface connector. When you push the AUX button, the PIE will show up on the display. I had a cabled style one on my 05 F250 to input a MP3 etc. into the trucks audio. I’d imagine they manufacture a Bluetooth unit.
