FlashGordonSD Posted December 14, 2008 Share Posted December 14, 2008 A few days ago I had to change out the battery on my 03 RX300. After I changed the battery the nav system doesn't work. Right after a disconnect a battery cable and reintall it the nav system will reboot (i wish i had the Japanese letters) and then starts to work ok. After I shut off the car and restart the nav screen is blank and it system won't boot up. Any suggestions. I did get into the unit in the back (after reading about it here) and ejected the disk and put it back, but it didn't make any difference. I've also check the 2 fuses. The radio actually works but after the radio screen comes up it go to the display screen. Help! FlashGordonSD :( Quote Link to comment Share on other sites More sharing options...
