ES300 navigation/stereo button problem

Looked at a used ES300 today that has the integrated stereo/navigation option and I noticed none of the buttons on the navigation console worked. All the knobs to control the tuning and volume work, as well as the touch-screen display seem to work, but the buttons on the right, left, and bottom portions of the panel don't work at all. This seems more like a systemic problem where a wire is loose to the buttons or something rather than the entire system being bad, but I am wondering if anyone else had this problem? I'm particularly curious how much this cost, as I will decrease my offer on the vehicle by a corresponding amount. Thanks so much in advance!

Also, if it matters, the lexus es300 was a 2003 model.

I am not familiar with the button layout on the 2003 ES, but some buttons only work when the engine is running and the car is parked.

The nav system buttons are integrated into the nav unit itself; there are no separate wires to each button. Your best bet is to take the car to a Lexus dealer to verify the buttons are not working properly and get an estimate.

Nav functions become unavailable at greater than 3? mph.

There are workarounds to be found on the net, but dealers are forbidden to implement them.
