i first tried to do that about a year ago and failed. the best reference picture i've found since then is the 3rd one at this thread
2006 PT Cruiser -Mac Mini - Page 2
today i just went there and pushed starting from the bottom. the bottom part came out very easily. there's a loud click when it detaches from the area under the radio.
and i think i can feel more latches then from what i see latch-holes in that 3rd pic mentioned above... but i may be wrong.
I tought i was just going to keep pulling from the bottom up to removing it on the top, but at the area in line with the top of the radio, it just wont bulge. at all.
just got blood under two nails and broke 3 plastic tabs while trying to use force. This is the best i could do:
Here's the bottom part, which i just pulled very easily:
and here's the part in line with the top of the radio... the damn thing won't move:
where am i being dumb here?
