I recently purchased a 2005 Toyota Avalon Limited. the vehicle has an auxiliary audio jack in the console but I can’t figure out how to make it work with my ipod – there is no aux button on the pillar and the system does have nav and sat (sat not installed). I have tried pushing all of the selectors twice to see if I could select an alternate source but that didn’t work. Any suggestions?
my 2005 Toyota Avalon LMT navigation system just stopped working and now the radio volume controls aren’t working as well. Does anyone know of anything I can do, short of purchasing a new radio, that might help me with this problem?
