The programming coding software offered here doesn't require that but the

At least from reading that's the way I understand it.
You only have to install the orginal in the trunk if you don't want to have this problem and the other little errors generated by absent units.
The Most Bus is broken when a unit is missing.
Since the Radio is essentially the most bus server its
pretty key for everything on the Most Bus.
Thanks for all the help here. Should any audio place be able to install through the trunk? Also... I'm having a tough time finding an exact part number match on the oem radio... would a radio from a different model year suffice? Or will the computer recognize that?
