I have the same isue with BMW CD Player CD53 E46 as "Hani" had (goes DISABLE when put it on the test bench,and I am trying to collect some Technical Information from BMW themself, I think it might have some wake up pin sent from the BCM or ECU to the unit to reactivate it back again if we know that code and the bus pin on the back of the unit then we are there!, this is what I am trying to track down , it would be much apprecaited if any body got into this matter
