I just bought a 2003 TL with navigation. The navi screen is black and the button controls alongside it don't respond. The dvd box in trunk will not take in the dvd. Everything else in the car (including radio) works perfectly. I checked the fuse marked "navigation" and it seems fine. I'd love some suggestions -- no owner's manual was included with the car! Thanks very much -- Joel

Do you have the security code for your radio? If so, you might just want to disconnect the car battery to see if something might reset itself. (That's a long shot but it might be worth a try.)

I'd take a closer look at the fuse (or fuses) for the navigation system. Test them for continuity with a multi-meter if you can't tell by looking at them.

Beyond that, you might want to invest in the Helm service manual for your TL. They're not cheap but they're worth every penny.
