Right now my car cannot accept Voice Commands for Nav. Just Phone.... I'm trying to figure out how to upgrade to this feature on my 2006 X5 with a build date of 08/2006. I'm not sure which module i have. Will i need to buy some new hardware? if so, which part number and how hard would it be to install? plug and play?

i've searched and couldn't find the answer that pertains to my vehicle.

thanks
