I have a 2010 Prius IV with the JBL radio. I have been offered a touchscreen radio out of a 2012. I've read in the forum that some are not compatible with the JBL amp. The number on the front is 57031 Model number on back is 86140 47050 Thanks, Rich
Since no one seems to know. Does anyone have he wiring diagram or pinouts for the 2010 JBL and non-JBL instillations and the 2013 57031 head unit?? Thanks, Rich
My best recommendation for you would be to spend $15 and go to techinfo.toyota.com and download the radio section of the Elecrical Diagram that you are interested in.
did you ever find out about this? I am interested in doing the exact oposite. Putting the JBL in a non JBL Prius 3
