Ok for some reason my batter died, I got a new battery and everything was working find.
The next day I notice my park assist was turn off, I tired turning it on by pressing the button and nothing happen. No beep sound and display in the dash
I also check the the menu and the park assist option no longer there.
Other then putting in the new battery I also add a bass box speaker in the trunk, power wire run from the passenger side since thats is where the batter is.
is it possible there is a fuse blown or something got disconnected??

 

 

If I recall correctly, as you are standing in front of your car with the hood open, it will be on your right hand side. Should be in a black plastic container with a cover that will open to allow you to slide it out. Hopefully another member will have a pic they may share.
