I have a 2006 coupe. I want to install the RB1 Navigation radio in my car. I am learning that there are two versions. One for Boston Acoustics/Infinity Sound, and one without. The only brand name I see in my car is Alpine on the subwoofer. Do I assume this means I need the NON BA/Infinity radio? Has anyone here installed the RB1 Nav unit in their Viper?

Thanks!
