My radio will not work after replacing the battery

Removing the battery in many newer vehicles will trigger the various anti theft features. Sometimes this causes the vehicle to do nothing at all, or it will start but quit, or you "lose" some of the accessories.

First check that the fuses are good, It uses the ones in the chart below depending on which unit you have.

Beyond the fuses, nothing shows in the repair info or the manual about it having a security lockout. But a call to a dealer to ask them wouldn't hurt, I have seen a few times when that information was not included and was "need to know/dealer only" stuff.
