I don’t want to say it’s impossible, but yeah it’s nearly impossible. All the climate control stuff is tied into the radio. I really wanted a non navigation ES but found one with Navi. I already had the Kenwood dbl din I wanted picked out. Only possibility would be to get the parts from a non navigation car convert yours to that and then do the upgrade. I really doubt it would be plug and play you would have to put in work to make it happen. So like I said suck it up and get used to the Navi lmk when you find a good way to add a usb input to it.
