I have installed many head units, so I'm not normally this retarded...however I'm trying to remove the PO's Panasonic DPG605, and I can't budge this thing. Any ideas? Does Panasonic use some other method of retaining the deck in the dash support thingie? Any help always appreciated! Solved! Man that was the worst impression of a 16 year old stereo thief EVER! Turns out the guy had solid aluminum angle going from the back of the deck to the firewall! That'll do it.
