Hey all, I've got a 2014 XF that I ended up unplugging the front impact sensor while working on the air box. Is there a DIY way to reset the dash light as its on now?

Also, my Nav system is totally dead. Nothing happens when you push the button and there are no errors being displayed. It worked when I first got the car and I noticed this issue a few weeks ago after I had to disconnect the battery to recharge it.

Any suggestions will be greatly appreciated.
