Hello please i have a Chrysler 300m & i tried to change the factory radio. I got the radio out fix the new one with a new cable connector, then the radio never work. After everything i discovered my side mirrors and my analog clock is neither working. I fixed the factory radio back to the car but it’s not working. I changed the fuse with another one and it’s not still working. Any ideas please. Thank you

 

The factory radio is one of a number of "modules" used in the PCI bus for these cars. Make sure the original radio ids properly wired first. Disconnect the battery for a few minutes and the system may reset. sometimes if you disconnect components like the radio or HVAC control in these cars without disconnecting the battery communication faults may occur.
