aux/mp3 not working

[mike z]

Hey guys just bought an 07 mited with jbl and navigation (e7009). The mp3/aux is not working. I bought it from a dealer so I can't talk to the old owner. I noticed that he had some work done on it. It the navi came from an 07 solora or camry. I took center console and all wires be running where they should. The wires running to aux were black/red/green/blue are these correct. Any help. greatley appreciated
