RX 330 2004 Nav system: Love it, use it constantly. BUT The street names on the turn guide have begun to blank out, leaving only turn arrows. Continues to worsen, and now street names blank out as soon as gas is applied, but reappear when totally stopped. Particularly happens from "route overview" mode and I touch the turn guide button that displays. Now other buttons are going blank on menu while driving - I am not talking about entering addresses in destinations which is a safety feature. Service mgr insists nothing wrong. Anyone else?
