If the display is not on when you turn the ignition on. First you check the fuses. radio memory is usually run with the courtesy light fuse. The main radio fuse is marked radio.
Second you pull the radio out and test the power leads to the radio. If you have no power then there may be a short in a wire.
If there is power on the power leads then the radio must be replaced.
Where is the PCM located on a 2005 Mercury Montego Premier?
It is located to the right and just below the power steering reservoir.
Disco Montego ended in 2005.
If the display is out, but the radio operates otherwise, the radio has failed.
Put in radio station and hit the set button
The radio display is usually tied to the dash board lights. As you raise or lower the illumination on the dash, the radio lights should change. During the day (with your headlights off), the radio display is at full brightness so it is easier to read in daylight.
i reconnected my battery of mountaineer 2005 and radio is asking for code, i wasnt able to find it any where...how to solve this issue
i work fro a Chevy dealer and when your display goes bad it means radio replacement time. if your dash light work and not the radio you will need to replace the radio
There is no auxiliary jack for any Montego or 500 for that matter. I was told by the dealer that "it has one somewhere". I bought the car and looked and researched, and found that it does not have one! You can buy a "Trip Tunes" accessory from your Ford dealer (this has no ipod control) or aftermarket. I bought an Axxess ipod interface made by Metra. It has ipod control and it works great for me. They do have an aux. only input interface as well. You retain your radio and steering wheel controls.
If you turn up your interior dashboard light settings, then the radio display will be brighter too. The radio dims to the setting for the dashboard when the lights are turned on.
There are 2 little buttons on the radio display one for the hour and one for the minute that you have to press with a pin or something sharp of some sort to adjust the time.
