I was fixing my nav screen because it went out. but when i fixed it my gauges and windows wont work.!!Help!!

 

Sounds like you blew a fuse or possibly a relay. Did you disconnect the battery before you started to work on the car?

 

The same thing happened to me a couple of weeks ago, it is a fuse definitely. According to the work order, they replaced a 7.5 amp fuse.. That should narrow it down... There is a box under hood also with some 7.5's in it...
