I SAW THAT SOME SCION OWNERS WERE HAVING ISSUES~ SO HERE IS AN ANSWER FOR THE IPOD NANO USERS
this Just in from TMS:

It has come to our attention that some iPod Nano users might experience difficulty connecting to the Scion upgrade radio with iPod interface. The problem occurs when a consumer tries to connect the Nano to the vehicle, song titles and all iPod features work but no sound will come out. The problem can be easily corrected by performing a soft reboot of the Nano.


Re-boot process:
Turn Nano on (unit should be disconnected from the vehicle)
Press and hold "menu" and "center button" until the apple symbol appears
Connect to vehicle

Note: On a soft re-boot no memory will be lost

Not all of Apple's tech staff seems to be aware of the problem or the fix; they may blame the problem on the radio. Please inform your dealers/customers of this problem and instruct customers to perform the re-boot before bringing the car into the dealer.

 

Good Catch. Good to see that Apple is on top of it.

 

Sounds like Apple isn't but Toyota is.

 

Thanks Scioneyes! You are now immortalized in our "Big Book of Stuff"

 

ahh that is the trick.. thanks

 

Good to know...lookin' into gettin a Nano

 

Damn! I wish I read this before I exchanged my black nano for a white one. I was having the same exact problems described and I even took it in to the dealership to have a look. No one could figure the problem, but now it makes sense.
