Ok, I know a bunch of years ago when the old ipods (pre-touch) were popular, they had devices that you could plug into your 3.5mm headphone jack and send it as an FM signal for car audio.
Anyone know what these are called? I need them to be useable either over bluetooth or 3.5mm or micro-usb (read: I have an android, not an iphone).
Any help would be great!
