Is there a wiring harness that will allow the AUX part to be used? I would like to place a BLUETOOTH that works like the SYNC that I have in my '12 Escape. I use an FM transmitter to play my music using a S3 phone. I did purchase a Motorola Roadster 2 for my Samsung Focus S, but it doesn't seem to work very well. Somebody suggested a head unit, but that would be a little more than I want to dish out. If you have a 500 SE, and you are using BLUETOOTH, what do you have? Thanks!

 

Not sure what's available for the 500, but my 05 S/D is using a PIE (Percision interface electronics) adapter cable/module to interface my MP3, GPS audio into the factory audio unit with AUX control..

 

Another idea just bit the dust. You have a link that dates back to 3-12-2011. That one is no longer available. I did some searching. The PIE FRD04-AUX does not exist any more. There is one, but it doesn't work on a '05. Perhaps for a BLUETOOTH I'll work on the Motorola Roadster. Thanks for your input!
