What is u connect did I make a mistake buying this jeep and my brakes make noise when you step on them what does that mean

This website explains the "U Connect" system: http://www.driveuconnect.com/ ---As far as the brakes are concerned, when you say they make noise...is it a grinding metal to metal contact noise or a rumbling sort of noise? Have your brake pads and rotors inspected to see what the condition of both are, since it sounds like you recently bought this Jeep---- I would say that you made a mistake buying the Jeep...Get acquainted with U Connect and have the brakes/rotors looked at....if these are your only issues, I don't see a cause for concern.
