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?
Nope. This headunit is not available to the public. The Toyota part no is: PT546-00160 and the Pioneer Headunit model number is: AVH-2558. Back in September last year when I bought the car and took apart the dash I contacted Pioneer asking for support in whether or not there were any modules that would create RCA jacks that would use any of the non-used OEM jacks on the back of the stereo... Pioneer's response was "contact the dealer, we do not support OEM headunits manufactured for car makers"
