Hi,I just installed the Alpine IVA-D300 and NVE-N852A in my BMW. Everything works great, but Alpine does not allow me to use the NVE-N852A menu while driving. I have to stop the car to enter new Destination, lookup ATMs, Restaurants.,etc. Does any of us here know how to wire the system so that I can do these operation while I'm driving. PS : I do have the PAC-TR7 wired to the system so I can watch DVD and operate the IVA-D300 while driving, but this does not bypass the protection mode of the NVE-N852A nav system. Any help is really appreciated. Henry
