We installed the Teyes 360 Arround View Monitoring System into the Nissan Elgrand awhile back. very happy with the results of this install.
For those looking to get this system installed, be prepared to leave your car for a full day or two as there is definitely a lot of work installing this system. A total of 4 new cameras and a head unit needs to be installed.
For cars this size especially, this is an excellent upgrade as it allow you to see more of the surroundings when parking. However, always double check in the rear view mirror and side mirrors too.
