Navigational (global Positioning System) Gps problems of the 2019 Honda Odyssey

From the date of purchase, the central display / infotainment screen intermittently turns off or loses connection (pictures of different messages appearing on the screen attached). When this happens, I lose the rearview backup camera, gps, radio, and the entire rear entertainment system, for which I paid a significant extra amount. While the vehicle was still under factory warranty, I reported this exact problem during my first and second service visits at Honda canyon. On both occasions, the service advisor stated they "could not replicate the problem. I specifically asked: "what happens if this gets worse after warranty expires?" your employee told me verbally that since the issue was documented as in the system, Honda would take care of it without charge. On xxx they did a software update (invoice attached). After that, the problem got worse. Current situation: the problem has now gotten much worse - the screen is unusable most of the time, creating a safety risk when backing up without a camera. On xxx, I met with service manager mark wiseman at Honda canyon. I provided printed photos of the different error messages shown on the screen. I left the vehicle for 10 days. No loaner was provided. Mr. [xxx] told me upon pickup that his technicians drove the vehicle "several times" and were able to see the messages but could not get the diagnostic code they needed. He stated he believes the issue is a device in the rear of the van. However, when I compared the mileage, the van was driven only 0. 6 miles in 10 days, contradicting the statement that it was driven several times. Most concerning, Honda canyon now claims their system shows no record that I complained about this problem while the vehicle was under warranty, despite two prior complaints. This is a pre-existing defect, reported under warranty, and is related to the known infotainment / most bus issues on 2018-2019 Odyssey models. The loss of the rearview camera is also a federal safety issue. Information redacted pursuant to the freedom of information ac.
