okay, so i upgraded my 07 stock stereo with the scion pioneer premium out of an 09. now the aux doesn't seem to be working... i also noticed that my blinker turned on for a couple seconds while i was messing with the buttons... soooo... wtf?

 

figured it out, i guess i have to have w/e device i use plugged into a power source as well. luckily i just bought a usb to cig lighter thing. weird tho, it didn't do that for the old HU. still don't know what the blinker thing is about either...
