my kenwood does it. anyway they only way then is to wire in a switch simply spliced into the power antenna lead. you'll have to run the antenna manually. i added a switch to mine anyway. i didnt want to burn it out from the antenna going up and down each time i scroll thru the sources though i think the hu has a 1-2 second delay. anyway, my pics folder has my switch on w/ the on-status blue led wired in too.
