Hi,

So I recently bought a 2007 CL550 that had been sitting for nearly a year. I replaced the front battery and the car turned on. However, I have electronic issues right now.
-Radio and backup camera don't work
-Windows don't fully go up
-Can't open and close the car (have to do it manually with the little key)
-Clock resets every single time I turn on the car
-When I turn off the car, the gauge cluster and all of the lights immediately turn off
Any advice on what the issue might be? Alternator perhaps?
