I've read here that there are still some issues with the BMW CB Radio when used with the VOICE II Com system. Can someone tell me what those issues are and whether or not there is an available solution? I'm still on the fence as to which system to go with, BMW, Baher, J&M. They're all pretty pricey and I would like to be relatively sure whatever I get will do what I want. That is, CB, Intercom, Cell phone, GPS, Radar. Seems like they all have their weaknesses.
