Greetings all! Running into my first (of many Im sure) issue while trying to build my AV system...I have a nakamichi IN-DV7 HU (flip out 7.5 inch touch screen) and I would like to use an Alpine NVE-872a stand alone nav unit. A friend said he doubts I will be able to display/control the nav system with the nakamichi. Anyone know if hes right? or have any suggestions?
