I have a 98 GS with nav. Today I started up the car and realized that the nav screen just kept blinking with the Lexus logo. All of the buttons except the top row of climate controls work, but nothing below functions. The radio will turn on, but only momentarily and continues to turn on and off.

Any help guys?

 

I dont know what the problem is....but I have a working Nav radio from my 99gs I sold. It has the screen and radio part. If you are near Pasadena, you are welcome to try. If you want to buy it, ill take 100. PM me if you are interested
