There is a thread on the IRV2 forum with all the info.
I can't post a link here but you can go to that forum, search in the Monaco section, for "Aladdin" and should not be too hard to find. There are probably a few here that have done the same - so maybe they will come along shortly and be able to provide some additional info too.
I know some have added a second monitor (just a video only monitor) for the Aladdin so they can see their backup camera full time and only use the in-dash receiver for entertainment.
