Hey guys, this morning I started up my 2006 Tribeca and noticed the Nav screen wasn't coming on. I restarted the car and tried the manual on/off button as well to no avail. I decided to drive without it and after getting to the end of my street (about a half mile) the nav system suddenly booted up with the Subaru logo animation and all seemed normal. Has this happened to anyone else here? Is this something to be concerned about?
