I have a 2011 ES 350 with no maintenance issues through 84k miles, until now. The navigational screen and all corresponding buttons don't work, including the trunk release. The following still works; lights,wipers, gas cap release, digital clock and temp indicators, and air conditioning although I can't change the temp or fan speed. Lexus stated I needed a refurbished navigation ECU and hard drive - to the tune of at least $2800, new system was quoted at $10K (seriously!). I asked if all fuses had been checked and was told yes. Work order stated "at connector E62 (navigation ECU), verified power at pins 1-3, and ground at pin 4." It's hard to conceive the system would blow so soon. Suggestions? I searched refurbished systems online and prices range from $250 - $600. I'm having another mechanic give a second opinion. I don't see another forum member posting this issue. Thanks much for any replies.
