Hi I was wondering if anyone can answer this one. As I currently don't have the user guide AKA Lexus Bible in front of me. Looking for the fuse that corresponds with the Navigation system to reset the system in order for it to read the hybrid DVD? I'd like to try this instead of disconnecting the battery.

 

The fuses are all over the car. Under the engine compartment covers on the drivers side, there is a row of fuses. In the driver's and passenger's footwell, there are 2 panels under the dash and on the driver's side of the trunk, there is another bank of fuses. Not sure which one exactly though.

 

According to the electrical schematic, there's three fuses for the NAV unit.

(IG) 10A ECU-IG RH
(ACC) 7.5A ACC
(BAT) 7.5A TV

The only one that is live even with the car turned off is the 7.5A TV fuse. So at least you have a name for the one you want. Not sure where it lives.

 

pull the "TV" fuse. this has been mentioned several times in this forum.

 

this would allow the navi to restart and update to the hybrid dvd? I have yet to get my hands on that dvd but just curious.

 

What if there is no "tv" fuse option? I've got a 2006 and am not seeing anything called TV. Any other suggestions?
