Question for Honda CRV owners
I have a navigation system in my CRV toad. I had to install a switch to disconnect the nav/radio from the battery; otherwise, my battery would deplete after a long tow.
My cousin just bought a used CRV to tow without the Nav system. Will he still need to disconnect the radio from the battery? I've never been sure if it is the nav system or radio or both depleting the battery.
