Hi,
If you havent figured it out already, it is definitely your venture cam. it talks to the TV in the AV system, it has a suction cup attachment , so that , believe it or not you can hang it off the front of the bonnet, so you can see the drop off - or over a front wheel arch to check that your wheels are straight ahead when you are in the really greasy stuff or in deep ruts. handy for newbies practicing. Mine has never been out of the glovebox since it was demonstrated for me. I suspect it would fall off with a decent bang.
I can dig out the instructions if you like.
Cheers,
Richard.
