This is a 3-piece set that was used in a 30 series Harrier. Image 1: Pioneer Rak Navi AVIC-RZ55 Image 2: Beat Sonic (for specific vehicle models) Image 3: Option: AUX and USB connectors can be connected from the side of the navigation system. *Normally, these are located on the back of the navigation system. The Rak Navi is from 2015, so the map data is outdated. It has Bluetooth and can connect with smartphones. I think it works fine except for the navigation maps. The Beat Sonic is necessary for adding the navigation system below the original one. I am selling this because I am changing cars. If you can use it, please consider purchasing it! *If you have a desired price, please comment.
