I can't hear you !!!!
Car Kit doesn't necessarily mean the phone got wet, but it does mean that there's a problem with the charging port. Most likely there's a lot of corrosion in there, and if you clean it out then it may get the phone working again.
The best way to clean your charge port is with some contact cleaner and a toothbrush.
If the problem persists after that, then you'll want to bring it in to a store and get the phone serviced or replaced.
