I just finished my install of my ISHD571 into my 04 TL with Nav and everything worked fine. iPod charged through it. I could play music, and navigate, control it, etc. Could switch to iPod, Aux1, Aux2, Sat, etc. Everything.

Then I disconnected my battery to replace the back lights on my steering wheel controls. When I finished that and reconnected everything, my head unit won't switch to XM at all. It's like it doesn't exist. I disconnected the battery again, and still no luck when the car started again.

EDIT: I forgot to add that the ipod DOES charge when connected to the gateway.

I tried searching and found one thread with no replies for this behavior, so I'm hoping for better luck.

Help?

 

Well, that initialization procedure you have to follow after first installing the iSimple (wait 3 minutes after power-up without touching the radio) must be followed EVERY time the battery is disconnected.

I had to disassemble the console again, unplug the vehicle harness from the gateway, and do it all over again.

Hope this helps in the future

 

good point... might try that... thanks

 

I didn't have to go thru that when I took my battery out when I installed my CAI. It came on as soon as I put the codes back in. Then again my is thru the navi in the trunk.

 

So what did you end up doing to resolve this?
