Very good
Replaced my RNS-510 with this one in my 2015 Passat (TDI SEL Premium with Fender Audio). I bought from the same seller a new backup camera. Everything was plug and play. I unplugged the CarNet module underneath the passenger seat along with the OEM Bluetooth module in the center console lid as the head unit comes with Bluetooth built in. I wired a new backup camera quite easily to the trunk. Remember to disconnect your battery before starting the process, as then the unit will recognize Fender that way. If I were to do one thing differently, it would be to wire in a rear USB to hide the wire. Steering wheel buttons work. Center dashboard (MFD) screen does lose the ability to show song titles, but that’s no biggie. Bluetooth phone quality is great.
