I couldn't find any info about the BE0869, but it seems the BE0879 is similar... may be plug+play replacement for 1432.
Becker Mexico Diversity CD 879 0879, BMW Mercedes Porsche NEW
New quality Becker Mexico Diversity CD0879 in original packaging. I bought the unit about 10 years ago for my Mercedes. I bought it as an unused device in original packaging. So it was never installed and is unused to my knowledge. All original accessories are included: receiver and amplifier unit; Cable sets; 2x code card; Instruction manual and Becker service brochure.
