I replaced the battery in my XJ* (04") and now it displays : config B on the information center? What is it?

 

Not sure about Config B but when I changed my battery I had to reset all of the windows by fully lowering them then raising them a couple of times. I also had to input the radio code.
The Gearbox will also have to re-learn your driving style.
Hope that helps a little.

So I installed bluetooth components in my wifes VDP and when I plug the fiber cable into tbe phone module the phone screen appears on the display when selected, but I get the "Config B" msg in my msg center and the red and yellow lights above it flash quickly. When I unplug the module the msg goes away.

Could it be that the phone module needs to be reflashed? I tried to pair my Doid X but don't know what code to use.
