Looks nice. I like the new silver trim pieces as well. I considered them.
Have you had an android head unit before? Takes a bit to get used to them.
How's the off axis view on the screen? Check your sunglasses as well. I had one of the many that oriented the polarizing filter the wrong way and resulted in a black screen when wearing sunglasses. Lol.
You want to get familiar with xda forums and find out if you can root your room. Get comfortable with using rst. Be very cautious about logging into anything from the unit. Often these units are older android mated to newer android and some apps don't like that.
Another issue is some don't manage sleep and startup well. You can add some power timer circuitry to keep the unit powered while the van is off at the gas station so you don't have to wait for it to boot.
See if it can use a powered USB hub. If you need to connect a phone these units rarely output enough good power.
