Hi there. I've looked at all the navi errors for the RX350 and the IS model and believe our 2009 RX-350 car has a different issue than the common glass screen connections. When the engine is cold, bumpy roads typically cause a new screen to pop up. The Route Trace screen pops up first followed by other random screens. Once a GPS position freeze occurred. Always fixed by pressing a non-map button or turning car off/on. Could this be caused by an intermittent connection(s) to the screen or a circuit board connector? Any other ideas? Many thanks for any help!
