Yeah plugged right in, same button layout and green lighting too. It might be out of a SD, just don't know.

 

This is what I use. Its just a transmitter.

if you ever get a chance, let us know what the part# is. real curious now.

 

If I can locate the removal keys I'll pop it out and get the p/n. Here is a pic though:

 

does that one play MP3s?

 

I don't think so.

 

That is what came in my truck. Would have been nice to know that I could have plugged something in the back. Oh well I like my Bluetooth. I believe I played burned CDs which prob were mp3 but would recommend u get someone to check that. Def not mp4 though.

 

What's the adapter that plugs in and where do you get it?

 

Brand is DPX, part number is: FRDN-AUX/S

Bought it from some random online retailer, can't remember which one.

It has RCA outputs so you'd also need a male-male RCA to headphone (aka minijack 1/8") cable.

 

Thank you! I'll have to look into that. It looks pretty simple.
