What am I getting into?

Have 1700 miles on the ’14 850 XP…on my trip this weekend, started hearing some chirping from the belt box, sounding like a turkey call, when idling. It got worse of the course of the day, now I can’t shift while the machine is running. Is this probably just a belt issue? Also, has a bit of a rough idle… If its just the belt, do I need any special tools to change the belt?

I have a big trip coming up and if it needs to go into the shop, I need to get it in asap. If its just the belt, who makes a good aftermarket one?
