2006-2007 Mazda 5 Info & Nav Screen: Fixing a Blank Display and Finding the Right Part

Variants: Standard Info Display vs. Navigation Screen

The 2006-2007 Mazda 5 was available with two distinct upper dashboard screens. These parts are not interchangeable, so it is critical to identify which version your vehicle has before purchasing a replacement.

Standard Multi-Information Display (MID)

Most Mazda 5 models are equipped with the standard monochrome display. This screen shows audio, climate, and clock information. It is a simple, reliable unit, but can fail with age. If your screen only shows this basic information, you have the standard MID.

• Common Part Numbers: C235611J0A, C235611J0B
• Appearance: Typically a monochrome (single color) LCD screen.

Factory Navigation Screen

Touring and Grand Touring models could be optioned with a full-color navigation system. This system uses a larger, color LCD screen to display maps and other vehicle information. The navigation system also requires a separate DVD player unit, which is usually located elsewhere in the dashboard and reads the map data from a disc. Failure of the navigation system can be due to the screen, the DVD player, or the map DVD itself.

• Common Part Numbers: C235-66-EV0, C23566EV0
• Associated DVD Unit Part Numbers: CC44-66-DF0A, CC44-66-DF0E
• Appearance: A full-color LCD screen capable of displaying maps.

Symptoms of a Failing Info-GPS-TV Screen

Failure of the information display is usually obvious. Here are the most common symptoms reported by owners:

• Completely Blank or Dead Screen: This is the most common failure mode. The screen will not light up or show any information, even though the radio and climate controls may still function. You can hear audio, but cannot see what station you are on.
• Dim or Faded Display: The screen may become difficult to read, especially on one side. This can sometimes be worse in cold weather and may indicate a failing backlight inside the unit.
• Garbled or Incorrect Text: On rare occasions, the screen may display jumbled characters or fail to refresh properly, leaving behind parts of previous text. This was noted on a similar-era Mazda with a Sirius satellite radio display.
• Parasitic Battery Drain: In some cases, a fault within the information display can cause a slow drain on the battery, leading to a dead battery after the car sits for a day or two. This issue is often traced to the 'ROOM' fuse circuit, which powers the display.

Diagnosing the Problem

Before replacing the screen, perform these simple checks:

1. Check Fuses: Verify that the fuse labeled 'ROOM' in the engine compartment fuse box is not blown. A bad fuse can cause the screen to go dead.
2. Check Connections: Forum users have reported that the wiring harness connecting the display to the main radio head unit can sometimes become loose. If you are comfortable removing the dashboard trim, check that all connectors are securely plugged into the back of the screen and radio.
3. Perform a Hard Reset: Disconnect the vehicle's negative battery terminal for 10-15 minutes. This will reset all electronic modules in the car and can sometimes resolve temporary glitches. Note that this will erase radio presets.

If these steps do not resolve the issue, the screen assembly itself has likely failed internally and requires replacement.

Buying a Used Info-GPS-TV Screen

Given the extremely high cost of a new OEM screen, a used unit is the most practical and economical solution. Here’s what to look for:

• Match the Part Number Exactly: This is the most important rule. A navigation screen will not work in a car originally equipped with the standard display, and vice-versa. Get the part number from your original unit before ordering.
• Inspect the Screen Surface: Look at photos carefully for any deep scratches, delamination (peeling), or cracks in the screen.
• Ask for a Functionality Guarantee: Reputable sellers will guarantee the part is in good working order. Ensure there is a return policy in case the unit is dead on arrival.
• Why Used OEM is a Good Choice: For a simple display unit like this, a used OEM part is often just as reliable as a new one, at a fraction of the cost. There are no complex moving parts to wear out, and failure is typically due to an electronic component reaching the end of its life. Aftermarket options are generally full Android head unit conversions, which are much more complex and expensive than a simple screen swap.

Programming and Installation

Does this part need to be programmed?

No. The 2006-2007 Mazda 5 Info-GPS-TV screen is a plug-and-play component. It does not need to be programmed, flashed, or coded to the vehicle's VIN. Replacement is a straightforward swap.

Replacement Walkthrough

Replacing the screen is a DIY-friendly job that can be done with basic tools in under an hour. A former Mazda technician noted the job takes about 40 minutes.

1. Disconnect the negative battery terminal.
2. Using a plastic trim removal tool, carefully pry off the long, horizontal trim piece that contains the screen and central air vents. Start from the passenger side near the glove box.
3. Disconnect the electrical connector for the hazard light switch.
4. With the trim removed, you will see a single 10mm bolt holding the screen assembly in place. Remove this bolt.
5. Pull the screen unit forward and disconnect the electrical harness(es) from the back.
6. Installation is the reverse of removal. Plug in the new screen, secure it with the 10mm bolt, reconnect the hazard switch, and carefully snap the trim piece back into place.

Cost Comparison

Prices can vary based on condition and supplier, but this gives a general idea of the cost savings of buying used.
