Update. I took my car to the dealer. Since I had seen before posting this that others had had a similar issue I'm passing along what I found out. Biggest take-away, the newest Nav DVD that can be used in a 2008 IS250 is 2012. I had put in a 2019 and it still won't eject. Some of you had resolved this issue through a combo of screen touches. FYI, the correct combo is touch top right, lower right 3 times. In my case, this didn't work. The dealer also detached the battery and performed resets; still wouldn't eject. They were only able to offer to replace the Nav reader/screen at a cost of $4000. If someone still thinks they have any other possible fixes, pls let me know
