vdo Siemens rd4 bench test help

[things4u2get]

Hi, please excuse my noviceness is perhaps recovering the obvious, but im trying to bench test a VDO Siemens rd4 cd player. Ive hooked to an LCD display following diagrams i can find of the web which include can bus etc. But both screen an stereo remain dead, i know there are drawing a current from the psu an i now they worked when they were in the cars. Am i missing something? another component for the can bus? Tried two LCD screens now.

any help appreciated.

Cheers

Yes, you're missing the car
RD4 is VIN coded and it needs to see the car...

Hi, thanks for your reply, yes i understand its VIN coded but im not getting the unit to power up eg take / eject a CD like the vdo rd3-01 models hooked up in a similar rig.

To power the radio on your bench you will need display and also a BSI unit...you can get one from a breakers yard.

Thanks! the missing part of the puzzle, will try to hunt a bsi down and give it a go. Cheers!
