I am confused. lol
 

Hey there..

I have gotten myself a 2000 M5 a few months ago, from my 02 540i sport 6 speed, and just LOVE it.

The thing that has me consfused is trying to get an AUX cable hooked up. on my old car I bought one from bmw, and plugged it in.

Can I do this with the C 43 radio my M5 has? or do I have to get one of those BM 53 radios?

Will the BM 53 radio plug right in?

I have done lots of reading and am still confused. I have upgraded to the newest nav computer and it works fine, but I cant figure this out...

Thanks for any info!
