Hi,

I bought a used 06 is350. Do I need to have a security code for my navigation when i change the battery?
Thanks,
Eric

 

There are no security codes on any of the 2IS radios or nav systems as far as I am aware. You'll be fine.

Honda/Acura models have a finicky security code, Toyota/Lexus do not.

 

Thanks,

Initializing the windows and sunroof (if needed) simply involves holding each switch
as each mechanism opens fully and then holding again during the entire closing
cycle and repeat, open/close. Generally not needed if you change the battery quickly
and can be avoided entirely if you use a couple of alligator clip jumper wires to keep
the current flowing.
