I need a bit of help trying to get power back to my head unit. I removed it from the dash to use the rear aux input, and now there is no power.

I believe i checked all the fuses. I read somewhere that you need to enter a code using a remote (which i dont have) any solutions?

is the unlock code needed when the unit wont turn on? Thanks

I've never seen a Sony head unit with an anti-theft code. I would bet your problem goes back to the fuses. Do you have a multimeter?

Im sure it has an anit-theft code, ive read about it in other forums... but they've said it normally says "code in" on the unit, but im not getting any power for it to display anything.

I dont have a multimeter.. :crap:

You need a multimeter, or at least a test light, for any serious troubleshooting. Your head unit has two power wires in the back; one red, one yellow. Both need to have power for the head unit to work. One of the two doesn't have power; and it probably goes back to a fuse. Check all the fuses in the vehicle, including any fuse box under the hood.
