My radio and navigation is completely dead after i replaced the factory battery on my 2007 chrysler 300c awd.also the key remote doesnt work at all.lock and unlock buttons on door wont work as well.checked all fuses and they are all good??help
Problem solved. Had to disconnect both terminals from battery .take fuses from radio navigation and PCM out while the battery was disconnected.connect battery. Cycle key and insert fuses back.this is the inly thing that cleared the radio from being locked dead.
