PCM memory error code

I just fixed 2 "defective" Kenwood 6" double DIN nav-stereos using my hot air reflow gun on the graphics daughter board. Use high temp clear flux on these around the EEPROM chips, like flood them (even make a dam around them with clay so the flux doesnt flow away from it. The solder balls are under these chips if there are no 'legs' visible.) . Don't use brown resin based flux, turns brown under heat and looks like pooh.
