I previously had a Springfield, and am considering another one once again. I currently have a Chieftain, and even though it has built in navigation, I use wireless carplay. In my opinion the functions you get out of carplay far outweigh what you can get from a dedicated nav system. I've been thinking if I go the Springfield route, I am going to get a wireless carplay screen like
@Joe21SBSS has. I wouldn't mind just using my iPhone but it appears that there is no way to pull carplay up on its screen (unless one of you guys can show me otherwise). carplay is designed to stream from your phone to another screen and not just be used on your phone.
