Be aware that adapters do not power then antenna booster and usually the instructions make no mention of this. If you want to hear AM/FM radio stations do some searching on that. It makes all the difference in the world.

I believe that the PAC RadioPRO does turn on the diversity amp. I have one in my 2003 and I was getting nothing from the AM radio until I did the latest firmware update which, according to PAC, fixed an issue with the diversity amp turn on. It does the JBL amp turn on plus steering wheel controls, as well, in one box.
