With navcoder, or any other type of program (modic, DIS, SSS?) would I be able to use bluetooth assist module in an e39 that never had assist. I know the assist wouldnt work unless I pay for it, but, depending on the price, seems worth it. The google maps sending pinpoints to your nav is great. Check youtube for google and bmw. I don't see why not since these all work on the iBus.
