I have a TL but I thought I'd post over here to see if anyone has had the same problem as me. Two days ago my stock headunit in my '03 TL started acting funny. When I'm listening to a CD, after a few songs the unit just goes into lockdown mode. So I turn it off and back on and re-enter my unlock code and it takes it. But it happened to me multiple times with a different CD almost each time. The discs are changing properly, and it starts playing properly. BTW I also have the USA Spec iPod adaptor. Any ideas as to why this is happening?

 

Sounds like it is losing power....my guess is a loose wire. Did it start right after the ipod adapter was installed?

 

The iPod adapter is causing it. The same thing happened when I had a Dice unit installed in my HU. I got tired of having to re-enter the code so I eventually removed it and am now using a cassette adapter. Unfortunately, our HU's are really glitchy, and I've yet to find an iPod adapter that works.

 

Nope, I've had my iPod adaptor for almost a year now. I've had times before when the system locked up while I was listening to my iPod or simply when I turned my car on, but never when I was listening to a CD.

 

Sounds like another Audio/Video question.

I'm sorry but you'll probably be better off asking there.
