I was able to update my 15 Trail to the 2020 4Runner stock radio.
Overall it does work and you can dim it so that it doesn’t blind you at night. The stock navigation is passable but I ended up getting a wireless carplay dongle and use that for navigation 90% of the time. It’s leaps and bounds ahead of the previous radio though. However I might eventually try the Sony XAVIER-9500ES since Trail Grid Pro has a kit for it. However if that blinds me at night then I’ll be back to the stock 2020 radio unfortunately
which wireless car play dongle did you purchase? Review of it?
