There was a thread several years back where I was upgrading my Head Unit in my 2013 Prius V two from 57010 to 57011. You had a thread where you upgraded to a 2015 unit. I recall that you had bought two of these units, because one had a scratch on the screen., and you offered to sell it to me. Do you still have it? It would be cheaper for me to upgrade the unit than it would be to update the 57011 maps.
