So i had to replace my battery couple days ago with a brand new exact battery. Everything went wrong when i made the change. It's an 02 Range Rover HSE. Im in california

1) a/c started blowing warm air
2) radio volume cant be turned up or down
3) the navigation screen is just plain white
4) the dash read (windows not set) = *fixed*

I took someone's advice and took the RR on the freeway for about 30 minutes at 65-75 mph with the a/c full blast. It's still the same with warm air.

Pressed all buttons on radio and nav. and got nothing.

Everything was fine until i made the switch. HELP
