It will be interesting to see if Toyota continues to use the same headunit in these cars for the 2017 Corolla iM ... if not then there will most likely never be any updates.
i don't think toyota issues the updates. You can get this Pioneer for any car in the aftermarket it just won't say Scion when it turns on. If you're ok with that there's probably software for that specific headunit and gracenote that needs to be found. does anyone know the model of the radio?
