I had the 430N with premium audio (factory Alpine amp and rear sub) and changed it out with the Alpine iLX-207. I used the existing sirius antenna and installed the module. I just used a backup camera from Amazon that mounted on the spare tire mount. I wanted the iLX-207 mainly for CarPlay. Works and sounds great. The unit comes with it's own GPS antenna and microphone that need to be installed and wires hidden, but both work great. I like having multiple Nav options (Apple Maps, Waze, or Google Maps) and multiple music options. The iLX-207 install kit also has the Maestro which gives you factory steering wheel radio controls as well as the ability to read vehicle info from the OBDP connection.
