can anyone tell me what this is?

[Praz]

this is on a 2000 x5 with dsp.
can anyone tell me what this little metal wire is used for?

heres a close up

it connects to the little white connection towards the left on the back of the factory in dash tape player

Radio antenna connection, the small one second from the left in your picture of the back of the radio.

[Praz]

i thought the black one to the left most was the radio connection? cause the connection that came off the black one is what i hooked up to my antenna adapter to fit the radio plug on my new heaunit.

[RichardP1]

Yes, there are two for some reason!

[Praz]

oh thats good then cause i dont have to worry about it. also this same small metal connection is on the 6 disc cd changer in the trunk. in this one, it connects the cd changer to the dsp unit or amp or whatever is back there. is this for power or something?

I believe this is called the DSP HiFi single coax digital audio cable. Depending on your vehicle it may or may not be used. See post #7 http://www.xoutpost.com/bsws-mobile-e...al+audio+cable Also remember to check the main page for information on sorts of subjects. http://www.xoutpost.com/articles/x5/s...er-bmw-x5.html

thanks man

Has nothing to do with DSP, this is part of a dual diversity antenna. DSP is handled within the factory amp.

Are you upgrading or replacing the radio?

[Praz]

im (trying to) replacing the headunit with a pioneer model but nothing else.

If you were driving an E39 I'd say it was the power and sub connection to your subwoofer as well as a digital coax. Since you're in an X5 I'll say I don't know on the big black one, but I'm sticking with digital coax on the little round one.
