I got the same thing by messing around the serivce menu. Wondering is there any solution out there? :cries:
I haven't found anything yet. I still waiting for a nice day to pull out my passenger seat, then the nav drive, then the CMOS battery in hopes it will default back to a useful state. I will certainly post if i find anything helpful.
Last night, I pulled the Nav ECU out from underneath the passenger seat. Opened the ECU and disconnected the SRAM backup battery (did it a couple times). I had no luck! Still showing the same screen. Wondering how other people in the club were able to do it by this way. I found a threah of one guy had similar issue and could only get it fixed by loading a newer version DVD. Really need help from whoever fixed the problem.
UPDATE: I FIXED IT !!!
Tonight, I followed the steps that RXCHICAGO posted in this thread (thank RXCHICAGO for sharing!) http://us.lexusownersclub.com/forums/index.php?showtopic=29621&st=30
and finally fixed the problem and updated to v7.1 as a bonus.
