You guys are much too funny
. I still never heard of this. Not saying it doesn't exist, but is a pic possible?? I'm assuming the radio is still in the dash, so this might not be possible, Carmine.
I just googled heat sink and it showed a few pics. It's that finned thing on the back of a radio. Says it transfers energy. I've seen that before on radios and never new what it was. Still don't know why it would be a problem for removal.
