Unfortunately, the Dual Mirror function only works with a limited number of cell phones. My Nexus 5 is not one them to my disappointment.
You should be able to connect a Sirius/XM tuner either through the front AV input or the rear AUX input
You should check that your HDMI and USB cables are plugged in completely at the rear of the AV614BH. I routinely use the USB port to charge headphones.
While you're in there check to make sure that the RCA cable from the rear view camera control box is properly plugged in. Another area to check is the control box located behind the instrument panel.
If your RV is still under warranty, your dealer should be handling your issues with the exception of the mp4 files.
The AV614BH is much better than what the manufacturers have been installing in the past.
That said, it does have it limitations. Despite its shortcomings. it has yet to irritate me to the point of laying out about $400 to replace it.
