Sorry for the dumb question here but I bought my 2001 530 last year from a private owner and I never really thought about whether or not to try & connect for a iPhone. I have the talking head icon on my steering wheel along with the R/T button on the wheel and the "Telephone" button on the radio. The only thing in the owner's manual is it talking about seeing the specific owners manual regarding this and I don't have that. How do I know if I'm able to use my phone or not? Thanks in advance!
