I installed my aux cable last week that goes in behind the screen and have the 3.5mm jack comeing out the ask tray with i plug into iphone/ipod etc.. however the audio level of the aux is soooo low compared to radio and cd (even with the ipod turned upto max)

anyone else experiance this? there a fix?
yes i can just turn the volume up but then the nav blasts out loud and if i switch back to radio and forget im deafened lol
