Does anyone know how to access the service menu on a 2010 RX450h with Nav?

I dont own the car yet so I am saying this through memory

try main menu, then info, then maintenance.

Thanks but I am looking the the "hidden" service menu. I know how to access it on older versions but that does not seem to work on the 2010 RX

Info + light switch on-off sequence.

ohh, sorry misunderstanding. Id be surprised if someone on this forum knows

it works the same way on the 2010, hold down the Info button (the left button in front of remote control mouse) then switch on/off headlights for 3 times, make sure you turn the light switch to the ON position not Auto.

i have tried on mine and it works fine, but no settings to change there, just diagnostics.

Thanks, interesting menu. Diagnostic only? Or can you make some changes? Do you think Nav firmware and software versions shown too??

pulp

the service menu is diagnostics only unfortunately.

you can see the nav version from the normal interface:

Yes, that screen in the Nav shows the software version, but that diagnostic menu shows a Nav version like 3350. Would that be the firmware version?

I have a Camry Hybrid w/Nav and was able to download a version that allows me to use the Nav features while driving. Is there anything similar for the RX 350?
