I went to Sam’s Club last weekend to purchase a new battery for my 2008 Chevy Equinox and have it installed. After they installed it, my car radio would not turn on at all. The clock on the radio interface had been reset to 12:00 when they disconnected the battery, but I could not reset the clock to the appropriate time after installation. After doing some research, I came up with two scenarios to look into:
-the fuse was damaged;
-or, the removal of the battery triggered a security lockdown on the car radio that requires a code to be inputted to make it operable again.
I checked the fuse, and it worked fine. I looked up the security lockdown item in the manual, and it explicitly noted that if this were to be the case, the interface would clearly indicate the word “LOCKED.” The interface does not indicate this. The only thing the interface indicates is the time, which is incorrect.
Are there any hypotheses as to why my car radio is now inoperable? And are there any suggested solutions for resolving this?
