MB radio - BT82.60-P-9309-01C
Model 129 as of 01.02.91
MODEL 129 as of 1.2.91
When the new generation of radios was installed two retaining plates (arrows) were installed on the sides in the radio shaft at the beginning (up to approx. 01/91)
The retaining plates were eliminated as of approx. 02/91, because the center console was modified correspondingly.
