Weird problem. Dash camera works fine in our Audi. But when we move that camera to the 2013 ES 350, it does not work consistently. Through trial and error, it seems the only workaround is to unplug the 12V connector after shutting off car. THEN, leave it unplugged when first starting the car. After the car cycles through it's Navigation, blue tooth connection, etc, insert the 12V plug.
While this works, it is annoying. Anyone else encounter this and have a better solution?
