I'm having problems with my radio in my 07 TL -Type S. The navigation works and everything, but the radio doesn't work. I am getting no power to it at all. When i hit the radio button, nothing happens.

HELP

 

dumb question but did you check the fuse for the radio?

 

I have a 2006 TL with nav, when turning on the car, the nav screen gives warning but the "Ok" button won't react when I touch it so screen goes black and the audio system won't come on at all. If I pull the Audio fuse, I can push "Ok" and the Nav works, then if I reinsert the audio fuse the audio powers back on. It works for a few days, then stops again. Only had the car a few weeks, seems pulling and reinserting the fuse isn't fixing it as long each time.
I did have a Grom installed through the XM input but all audio was working fine before and for several days after the install.

Anyone with ideas?
