I just added the 2018 UAQ to my 2015 and used Alpha to turn on the cargo cam which I am using as the front camera and it works great. Once you do that you can use the on screen buttons once the camera is activated to toggle between the front and rear cameras. Until I turned on the cargo cam these buttons did not show on the screen. Which makes sense since there was only one camera the computer new about before. When in motion I can turn on the front camera at any time and it will stay on for 10 seconds (per the manual) before auto turn off which is what the cargo cam is programmed for and it can't be changed.
Only Gen 5's now come with a front camera (and other ones as well) therefore for us 4th Gen guys I HIGHLY recommend anyone that does not need/want the cargo camera to use it as a front camera instead. It makes parking much easier in my opinion and is just fun to view when driving for a few seconds. When stopped (but still in drive) you can toggle between the front AND rear cameras which is kind of nice if you think someone is getting to close to you from behind. This one:
