I upgraded my 2018 head unit to a OEM GPS model but it is not recognized in the Toyota app and no ra

I upgraded my 2018 head unit to a OEM GPS model but it is not recognized in the Toyota app and no radio apps will work. I spent about 25 minutes on the phone with Toyota. They determined that they could not help me because I did the head swap myself. I have since learned through trial and error, that the Toyota app for my old radio did not show the APP SUITE within it. After the upgrade, nothing changed on the Toyota app on my phone, and the only way to get the APP SUITE on the phone Toyota app is if I can get someone to change the radio serial number and ID within the Toyota system concerning my vehicle. Basically, the new OEM radio won’t work because it came with a poorer unit, and that’s all the Toyota app will support.
Just an FYI, I deleted my Tundra from the Toyota app on my phone and installed a serial number of another tundra that had the same radio. It showed the app sweet then. However, it wouldn’t work, probably because they need proof of ownership of that particular serial number. I hope this wasn’t too confusing.

I feel sort of stuck, because so far no one has been able to help me. And, no, I am not up to spending the money for an aftermarket radio which would solve all of my life‘s problems .

 

Did you ever work this issue out? I'm about to upgrade my non-gps unit and it would suck to not have the apps work.
