Thanks for the input. I will have to have that looked at.

I have a 2000 RX300, and it does not have a navagation system with it. It does have the screen with the A/C, radio, CD, Information, Temp, etc....though. I am interested in finding out if there is any way to have a navagation system upgraded to this, and have one added without it being a huge expense. And wondering if this is even possible without just having to replace the whole system. Any input would be appreciated. Thanks.

I have a 2000 RX 300 as well, and my clock was doing the same thing. It was the battery that was bad. SO get it checked before you get stranded somewhere. I got in my car to go to work one day, and it wouldn't start. Had to get a new battery.

I recently bought a 2000 RX300 and I notice a hissing sounding noise which sounds like it is behind the speedometer, dash, etc......it is intermittent and goes in and out. Does anyone know what this might be? It only does it when the A/C, Heater, etc..is on. Thanks.
