dvb-t in w203
 

Hi all,

My first post! I am from the uk and have a pre facelift 2004 w203 c class.
I am installing a dvb-t system to my comand 2.0. I want to install the tuner in the boot but I need 12v for it. Also, I might need a powered aerial (9v) as well - also to be kept mainly in the boot or on the back shelf. (aha! boot = trunk btw!!)

questions:

1) How do i remove the carpet so i can thread the wires through to the comand ?

2) How can I get 12v and 9v which is only on when the key is on?

3) er,, thats it actually

thanks

Steve
:silly:

The rear SAM (signal aquisition module) is on the left inner fender and has power from the battery. I never tried to penetrate the bulkhead so can't help you there. The SAM is incorporated into the fuse panel.

thanks Steve - would this be always on power or only on when key is in ignition ?

Thanks
:)

:eek:

Both batt term 30 and ignition term 15 appear at the rear SAM. If you understand that terminology then a good wiring diagram will tell you the rest of what you need to know to tap these circuits. I didn't reply before as it would be unprofessional of me not to warn you about tying into these systems involved without a thorough knowledge of what you are doing.

The SAM is a finicky device and I've seen as little as running the battery down do it in.

thanks very much Steve - much appreciated.
