Dennis, which ever system you buy, if you have to buy a monitor, buy the largest one available. My neighbor drives a Toyota Highlander and it came with a small monitor making it difficult to use. My Honda Pilot, which is several years newer, came with one that has a larger monitor. The first time my neighbor rode in my Pilot and saw how easy it was to use the larger monitor when backing up, he stated his jealousy.
BTW...I am not selling Hondas Pilots or denigrating Toyota Highlanders. Both are good vehicles IMO.
