Ok does anyone know what if any radio with the nav and everything (persay the entune) will work from a 2012 in a 2011 4 runner I want to upgrade and right now I have the standard unit ( dont know if there are different units but mine has bluetooth party mode and ipod hook up if that helps and I would like to stay with a unit that uses the toyota controls) I dont believe it has a sub. I want to keep the stock look but the toyota dealers 3 different ones that I have talked to said I would have to have a vin# as if they cant find one lol at The dealership. and that it would be like 2k for the unit that I can't send back. Anyone that has changed out there unit Help Please. I like the functions of the entune but if there is something better out there I am open to suggestions for that as well!
