Don't have a 2010 to look at but the dome light circuit should have power all the time, it comes on when you open the door.
You should be able to turn dome light on with a switch on the dash as well, i. e. dimmer knob on some.
See if Map lights work when Dome light is on.
I only see 1 "interior light relay" with 15amp fuse, and thats "alot of fuse" for 1 bulb
If not then they may have a separate fuse and you will need to find that fuse, it only has power when key is on, you need to change that to give it power all the time.
But if you change it to full time power and you leave map light on it WILL drain the battery
