Bluestar not working after car battery dies

[whatthe6789]

I recently had the battery on my 2007 Impala go completely dead, and upon replacement, everything in the car works except for the Bluestar. I have disconnected the unit and let it sit for a while and then re-connected to no avail. Anyone had a situation like this, and how did you reconcile the situation?

Thanks!

Sometimes a battery drain can effect the program memory. Usually re-installing the code can fix the problem.
If the bootloader got corrupt, you might have to send it back to the factory for re-programming.
