I'm trying to install my Alpine double din but I'm having trouble taking off the vent trim and others pieces to get to the stock radio. I looked at the guide on the metra site but couldn't even get the drivers vent off (I don't want to break any tabs or anything) could anyone help me? Also dumb question but where is the 12v battery? I always like to disconnect the negative before installing anything electrical. I was like looking in and under the trunk and around in the engine bay but can't find it. Lol thanks
Ok I found a much better details guide with colored pictures. But I still can't get the drivers side vent trim off. I put a thin metal piece to try and pull it out by pushing down then out. But all I'm doing to destroying my trim piece. Anyone have problems like this?
Regarding the trim that is over the air conditioner outlets: you just need to grab the top and bottom with your two hands, and pull the trim out horizontally. No need to push down. In case you didn't find the 12V battery yet, it is located in the hatch, right rear corner under the triangle-shaped hatch floor piece.
I'm actually having the same problem getting it out, try as I might, it seems very solidly wedged in there.... I'm thinking that I might have to loosen some screws on the trim piece below to free up the vent trim a bit more... edit: found a better guide to take the vent out - going to give it a try later on: http://www.eaa-phev.org/images/d/dc/Stereo_Accessory_Install_Guide_04_Prius_v1.03.pdf
Ok, you need to push down on the top part while pulling toward you in order to free it. Then sorta keep pulling toward you, and you should eventually pull the piece out. Here are some pictures of the clips that hold the vent trim on: upper piece: lower clips:
