New Prime Advanced. No AM or FM but XM works?

When I tried them, I found the radio controls a little confusing. My memory is they are heavy into "seek" mode and could not find a regular tuning dial.

Let me suggest re-reading the Owner's Manual section and doing some 'open book' testing. If it still doesn't work, you'll be able to show the problem to the service rep including chapter and verse.

there's a method to have the radio built a station list (it will prescan the entire frequency range and build you a list of everything it can hear, along with the rds identifying data if it has it. kind of handy really). if you do that and it shows up nothing, theres probably something wrong in the radio (antenna, lna, mixer, etc.), you'll need to have the dealer fix it. heck, I live right near NYC. I can usually pick am up without even having an antenna connected.

 

I also had to do a channel scan. Both AM & FM worked before that if you went directly to the station number.

 

Regardless of the cause, it's still under warranty. Take it in.
Assuming that you have tried a "seek" on both bands and it finds nothing.

There may be a different antenna connection for AM/FM versus XM.

P.S. Remember that letting the car sit with your new alarm ENABLED will add a significant battery drain and you may not be able to leave it like that for more than a week at a time.
