I just installed a new stereo in my 2007 Prius. Replaced the original head unit. Got everything installed and working properly, reinstalled my dash and my A/C controls and Battery meter do not work. does anyone know if it's because of the unused plug (that used to go to the original head unit)?
Did you use a 68 ohms resistor ? follow this link and read page 6 and 7 http://documents.victorytechnologies.com/documents/product/3563.pdf
