Thanks for the response! I saw that chart during my endless searches but I'm not the most electronically inclined!

Let me ask you this...today I took everything out, cd changer, nav ect and hooked everything back up. Just prior to that my obc screen had been showing the phone but then it too now is not showing up.
If there has been a break in the ibus, is there a way to get it to recognize the radio and dsp again?
Like I said in my earlier posts, the nav works though I have no voice nor does the radio controls show up and now the Bluetooth.
