Check to make sure your vehicle does not have a factory amplifier. If you used a fit kit with wiring harness. try looking at how many wires were used in the factory unit compared to haw many you are using now. see if there are extra wires in the vehicle. If there is extra wires it is a pretty good clue the vehicle has an amplifier and will have to be rewired.

reinstall the factory radio use a digital volt meter to see witch wire supplies voltage when radio is turned on and off, note placement on harness then verify this wire is hooked up on the output side aftermarket harness you may have to jump it to get the maps to turn on. tip you can carefully pull unused wire from harness example (dimmer wire orange white) and move it to the position needed to keep it a clean install .

You have to isolate yellow-black cabel. This cabel was in contact with earth and it was the reason, why you have Mute on the display.
