Last week we bought a new GX460. Last night, the guided navigation froze after I had pushed the "yes" button whne it asked if I wanted it to replan the route to avoid a traffic jam. It immediately froze and the whole Nav system was unresponsive (radio system, Nav, climate, etc.) until we turned off the car about 40 minutes later and restarted the car. Is anyone else having this issue? What might be causing it (I read some older IS models had problems with the connector?) Any cures? We expect to take it back to the Lexus dealer to fix it, but want to know if this is a recurrent issue.
