The CIG fuse in your 05 is supposed to be 15A. If you blow it, you lose power to that power outlet and the radio, so nothing safety critical. The fuse is in the under dash fuse block, which is inconveniently located. I know, I've blown that fuse a lot over the years.
For what its worth, in 05 they dropped the 12V outlet in the console between the front seats, and its fairly easy to add one

It is fused by the under dash 15A PPOINT fuse, which doesn't take out radio power if you pop it.
