Hi I'm a new member to your forum. I just purchased a 2007 R320 CDI manufactured in the US and it's loaded. I have a question for those of you that know something about the voice activated navigation systems. Radio, CD and IPOD My R320 has the hands free phone, the voice button in the steering column, Navigation system, 6 disc CD changer and the IPOD cable in the glove box. The invoice state that it has the PO3 package. when I purchased the R320 I thought it had the voice activated system that allowed me to control all systems with the voice control button. I'm now told that all models come with that button but I don't have the voice activation system. So with all that being said, how do I get this system installed? is there an after market system? were do I find it? how much does it cost? I hope some one can help me.
