how do you work or program it to where you can use bluetooth for my stereo phone?

...well there's a USB connector, (or is it a RJ-8 or RS-232?) that snaps into the device and can be selected from the rotary selector (if a JVC)...personally find it troublesome as you cannot keep your eyes on the road, press the menu, select, page thru a bunch of artist to get to a single one...tis the legacy of the passenger....driver has to pull the hell over, out of traffic where he can dedicate his full attention to this device. honestly, use an mp3 CD, you can get half your library on it, and won't come tumbling out of your pocket onto the granite floor and be destroyed, along with all your favorites....damn these things have broken my heart, cant live with them, can't live with them.
