Quick question...

Can anyone tell me how the stock changer is connected to the HU? Is there a cable that connects the two or is it all internal? Maybe someone has a picture of the backside of the audio unit that might help? I have a 02 TLS w/navi.

Thanks in advance...

 

there are three harness sockets on the back of the head unit: the main one to the car (power, navi hookups, speakers, etc.), the one to/from the Bose eq, and the one for the cd changer.

 

So...the CD changer does actually have an external connection to the HU? I was told that all the connections are internal...

 

Internal to what? It's a separate unit you can buy from the dealer, so there must be some way to hook it up. (You have to remove the factory radio to hook up the cd changer). It's the lower-right harness plug-in when facing the rear of the head unit (right next to the main harness).
