Broken navi system?
 

My 07 TL's navigation system and radio are acting strange. Symptoms are:

It takes a long time for the navi to boot and get out of the disclaimer message screen. The "OK" button does not respond at all.

Even if the map shows up, unable to access any of the menu, audio screen, etc.

The upper dash radio station, volume information does not display information, though the radio works. Just can't see which station it's on.

CD player works.

So, is my TL's navi system shot? Time to call Alpine and ask them to fix it?

Thanks!
