I have just recently lost all the street names on my Navi (2005 TSX), its shows only a few names on the map, but when i click on them with the joystick i can see them. And sometimes the map puts me in the middle of the field like a mile off the road i am on. I have tried resetting the system (maps/guide/cancell buttons together to get into the systems) and i have taken out the DVD and put it back in to reload , still nothing works. Any help would be great.
Cheers

 

Typically most honda navi units in general, the TSX included, are pretty solid. Motortrend did mention in one of their first rewiews of the car the system was "quirky". There isn't much you can do when electronics start truly going hay wire. It's an expensive option at 2k+/-, if it's still under warranty as it should be I'd consult the dealer at this point. You can find other possibilities and common issues/costs with the tsx navigation system here tsx navigation problems.
