Ok i searched and searched for an answer but had no luck. My mom has an 03 TL that i installed a usaspec aux in and ran both her sirius and her ipod. It has been working for a year or so and then she said hitting the cd button twice wouldnt switch it. Right around this time she had a new battery installed in her car and the input magically started to work again for a month. Now the stupid thing wont switch to the second cd input (CD2 or whatever) so that she can listen to her IPOD. Could this have anything to do with the battery or was that just random? I have pulled it apart and made sure everything was plugged in tight but no luck. Any ideas?

 

any help?
