Most likely, yes. Any time your car is flashed, it will overwrite any tune on your DME. In this case, for 2020s, it would likely soft-lock your DME requiring a bench unlock and re-tune.
Good to know... so basically its gonna cost me another $400-500 just to get wide screen carplay if the above works...
Well that's unfortunate...and seems odd given that we know there is actually an updated software version out there...at least for the 2021s.
So they lied to you about software being sent? Why would they even do that
I have no idea. It's a wizard behind the curtain situation. I've not been able to speak with whoever it is at the dealership that spoke with Toyota. Yesterday a service coordinator told me that the service manager told her they had been sent the software. Today the service advisor I dropped the car off with told me there is no update. My last two conversations with the service advisor have led me to believe that he has no idea what I'm talking about.
I was also told that there was no software update yesterday. I wonder if the service folks just haven't gotten it yet.
Toyota seems to not know what the hell to do with these cars, they say yes adn ok to one thing and they say no sorry in the end. When I bought mine I had a battery error due to the car sitting in the lot for a while before I bought it and they only one had tech that could override the message. The guy only came in once a week. And then they called me to bring it in to get detailed because they couldnāt do it the day I bought it. I brought it in and they gave me a rental, they took a couple of days because they were going to āleave the car as if it just left the assembly lineā when I went to pick it up the car was dirty. I filed a complaint against them with corporate and they took care of everything right away and sent me an Amex gift card in the end.
