Emack, have you tried either Pandora or MOG besides BMW Connected. Also, all apps need to be up to date at all times. There are a lot of changes that Apple pushes out every few weeks and the apps need to be updates to accommodate for them.
Also, have you tried connecting with the white Apple iPhone cable that came with your phone?
