Is it possible to have the Ipod kit from BMW installed on my 05' 4.4i without DSP but with NAV? I have a cd-changer and dual DVD player with headrest LCD's. Also, if I can get this installed does the Ipod menu come up on my NAV?..can I get it to? Can I get it to come up on my rear LCD's..I'm new to all of this..I'm picking up the vehicle tomorrow..
