The problem is - GPS (Nav) console and the cost: New - $6,000, Rebuilt - 1700. If your GPS goes blank that is your problem. The reason the heating/AC and clock also drops off-line is Lexus designed a single-point-failure. Because you can adjust the heat/AC and the clock using the GPS touch screen, the GPS fails the rest fails.

GPS keeps flushing the Lexus sign and then turns blank. Also the radio is not not working. The clocks shows time but it is not the correct time. Looking for how to fix it without having to get it to the Lexus repair shop
