Yours is bigger than mine was. I had a 13 in Audiovox and I took it out and put in a 19 in flatscreen. My opening was trimmed out with padded facing. After the changeout, all I had for trim was a single piece hardwood DW stained and I put on. The original padded facing was discarded as it did nothing to hold the TV and was not needed anymore. The 19in flatscreen covered up the 15 in square hole. Part of the back of the new flatscreen actually resides in the hole. All the connections are made up and the cables come through an existing hole in the overhead compartment passenger side. It works well for me. I built my own mounting bracket and did not buy the $100 dollar mounting kit. Thought that was nothing more than a rip-off. Got mine at a big box store.
