I have an LS430 & a SC430 both from Canada. As i now reside in the US I would like to have my temperature displays in US ie Fahrenheit for outside temp and AC setting temp. I understand this involves changing AC CPU's Could anybody advise me as to the CPU numbers I require and the degree of difficulty involved in changing them?
Thank You
Douglas
(too bad this couldn't be done with a button push as in every other car, Toyotas included)

 

If I remember correctly, there was a way of doing this via pushbutton/press combination. You might not have to buy another CPU. Ask one of the Lexus techs...it should describe this in their service manual. It's not a well known "trick".

Thanks for the advise, will try talking to them again but the last time I asked they just referred to the C-BEST settings which don't cover that..
