where to put in for my usb car charger
 

i bought a lexus es300 2001,no blue tooth function, so i bought a usb car plug in charger, where should i put in, is the lighter ?

You might want to try posting in the ES 300 forum as those owners might have some other suggestions. This is the LS 430 forum. That said, since it is designed to plug into a cigarette lighter you should plug it in to the lighter receptacle.
