Hello all, I have a 2015 final edition equipped with a factory installed Rockford fosgate system. I'd like to install the OEM nav unit to keep it as OEM as possible. I know that the 2014/2015 nav units will fit and is a plug-and-play install with their corresponding install kits. My question, will the Rockford fosgate system still work? I have heard that because these nav units have built-in amplifiers the two will not work together. Probably why all Canadian models with RF never came with navigation? Has anyone managed to have both installed without issues?
