I have been reading up on how to do the upgrade (to add perspective view) but it looks like i need to install software version V27? If I already have V50 with my Mk 4 system will this be downsteping the system? Why cant I find perspective in the sub menus for my current V50 system? I know cars and not so much computers so that translates into me being clueless on what to do here?

HELP!!!
