*** BEFORE & AFTER PICS UPLOADED *** Tomorrow I am going to have my gauge faces changed from black to silver (NA Auto version). I have read in some places that I should take off the negative terminal before removing the gauge pod.
So here is my question:
Do I HAVE to remove the negative terminal to make this work? If I don't, will I fundamentally screw up my pod?
I just don't want to if I don't have to (lose all presets, settings, xm will have to be reflashed, etc.) I don't have the stock radio in, I have a Pioneer AVIC-N3.

Thanks for any input!
