I own a 2019 Toyota Highlander. I have been in contact with the dealership every year since I purchased it to update the GPS. The dealership keeps telling me it's coming out next November. Last November they sold me the updated chip for $165. It was exactly the same data that my old chip had. They gave me a refund and I returned the chip.
Today I called Toyota corporate. At first they told me 2019 Highlander did not have a GPS option. Then they did looked up the gps and said they were no longer supporting it. I asked then to confirm that three times and they said they were no longer supporting that GPS. It's a terrible thing when cousin's marry.
