Radio question

[ncrooks]

I took apart my dash today to change a bulb in the climate control panel and I found a box that said dual pole fm transmitter with some wires coming off it. Didn't know if this was stock or something previous owner may have added. Looks like it may be a aux or Bluetooth input?

FM Modulator? Yeah, could've been for a bluetooth kit or even a rear DVD (or whatever the previous owner used it for).

EDIT: NO "fm modulator" comes from the factory.

I do have read DVD player maybe that's what it is for
