Maybe someone has solved this before, my radio is not ML type, and has navigation unit that has " no disc found". But radio was working on am/fm and sounded nice.
Also cd and cassette worked ok. Now only the cd and cassette works and when am or fm buttons on head are pushed nothing happens. Have tried to run diagnostics for
radio but since navigation doesnt work I cant push the screen to open up any screens for viewing radio diagnostics. After looking at how the different components go together
I see the radio is just a control head and the actual am-fm tuner/ amplifier are in the trunk. Has anyone had luck on deciding which unit is at fault without the choice of actual
swapping out with good units which are not available ?

So Ive bought a tuner/radio am-fm unit from ebay, p/n 86180-50040. Ill swap it out and let you know if I made right choice. Im also
checking on updating my navigation dvd to a gen 4 unit and see if that will allow diagnostics to be run on the audio system. I hate
this error message " disc not found"...
