I have an 2001 E320. I have the Bose system with no navigation. I want to install a factory e320 navigation command module. Someone is willing to sell me one for $800 and says that all I need is 2 connectors which I can purchase at the dealer. Is this right? Will everything work well together or is he just trying to sell me something? Will the dealer be able to "DeCode" The Navigation Command module? Any info greatly appreciated.

Thanks
