So three questions:
I was looking at the product on the AM website and one of the customer photos of the bottom "button" on the right side makes it look like it's merely a cover; it seems to have a single hole, so is it actually used, or can I use it? (image here
I was seriously considering just buying two backup cameras (one front, one back) and putting a switch where the cover is to toggle between them. For my purposes, it would be much better than the front parking assist on AM, and I could keep a backup camera (one of my main reasons to buy the kit).
Is there any ability to change the maps or software (SW) on the kit? I'm currently using a Garmin with traffic awareness, and even that has trouble sometimes in the bay area (tons of roads packed together), so I'm a little hesitant to switch over to some third-party SW (however great it may be). I did a little research on the Rosen unit, and it seems that other users have been able to substitute their own maps from Garmins, etc. (though that unit had an SD slot).
How do the RCA inputs come into play? Just looking at the install guide, I don't see them exposed anywhere (there's no slots in the bezel). Is this something that we place at our discretion? I'm trying to see if anything can be connected via RCA and use the screen.
