Cup holders and reversing cameras

Hi all. I am the proud owner of a 94 t4 autosleeper. As nice as it is it's a nightmare to reverse and with it having the 2.4 non turbo engine their is more often than not someone right up my chuff. I'm after a reversing camera that acts as a rear view mirror. Any recommendations would be greatly appreciated. 
Also, any suggestions on where to put my brew whilst driving would be good. 
Many thanks

Hi, I have had one of the Chinese reversing camera systems on my transit for over a year, and it works great. Bought from EBay. And wired to come on when ignition is on, so used as a rear view mirror. You can get them with extra long cables, meant for vans and trucks.
I wouldnt bother withe the wireless ones.

Have a look at EBay item number.
