Is this how they are done???


step 1
turn the key to 'ACC' and turn the radio on. now, turn the key off
.
step 2
on the radio, press and hold 'MUTE' and while continuing to hold down 'MUTE', turn the key to 'ACC'. you should now see a horizontal line on the head unit lcd display start to flash. you can now let go of 'MUTE'.
step 3

within 15 seconds, press and hold 'PRESET 1' and turn the key off. you should now see a flashing cursor with the letter 'A' displayed.
step 4


now use the 'PRESET 3' and 'PRESET 4' buttons to change to the letters/characters you want to use. when you find the letter/character that you would like to use, press 'PRESET 6' and the cursor will move over to the next position. if you need to delete a character, press 'PRESET 5'. once you have complete your message, press and hold 'PRESET 6' for five seconds to confirm your selection.

*note*
there is a 16 character maximum for the welcome message for the 2st gen hu.
you have 60seconds to enter your message, after that runs out u have to repeat steps 2&3 to pick up where u left off. i reached the 16th character of the message and held PRESET6 to confirm, and it cut off the last character,, i repeated those steps, added the last letter, and just let it sit til the 60seconds ran out and it stuck

 

I hope i'm not bursting your bubble, but changing the welcome message is something that could be done on ALL scion headunits. I don't think I could consider this an Easter Egg b/c i found out how to do it in my stereo manual.

 

and wiith this u change anything on it.
