We never use the cup holders in the center console, Myra and I each have one beside our seats. After I installed the doghouse insulation I put the cup holder/tray assemble back in place but I kept think of ways to have a better tray in the center, plus I'm always kicking the tray portion getting in and out. Today I removed the tray (only has three screws under the rubber mat holding it on).
I used the tray as a pattern and cut a piece of heavy rubber shelf liner I had left over to fit. I used several small pieces of double sided carpet tape to hold it in place. I think I'm going to like not having the cup holders and having a nice big flat tray instead.
