DIY: How to Replace LCD Glass on BMW E38 / E39 / E46 and E53 X5
- 1995 - 2001 BMW (E38) 7-Series
- 1996 - 2003 BMW (E39) 5-Series, M5
- 2000 - 2006 BMW (E53) X5, X5 M
** 1999 - 2006 BMW (E46) 3-series removal from dash, and assembly is slightly different.
The most obvious symptom of a failing navigation lcd are observable defects such as streaks, blotches, blemished, darkening or fading, washed out image, etc. Even physical impact to the glass causing it to shatter or crack. We have even seen LCDs that have been coated with dash cleaners and then left in direct sunlight for extended periods of time causing the glass to caramelize.

Removal / Disassembly Procedure
- Remove Plastic Trim Frame. Use a dash trim removal tool to pop off the trim surround, it will unclip from the navigation.
- Remove 4 screws around perimeter of navigation. The top 2 are on outmost corners and are either a philips screw or T10 torx.
- Disconnect blue and white plugs from rear of monitor. Press Eject button so monitor is open before removing power. The first cable is a large bundle of wires terminated with a large blue connector. To remove the connector, slide the white locking lever down and away from the cable end so that it mates with the case of the controller. Do NOT pull either connector by the wires. Remove from dash. Reach into the hole in the dash left by the navigation and pull directly out.
- Prepare a workspace suitable for electronics rework including ESD protection. Make sure your workspace is of adequate size and has bright lighting, a magnifying lens, soldering and desoldering equipment, and most importantly, an effective means to prevent electrostatic discharge (ESD). This should, at a minimum, consist of a properly grounded wrist strap and an anti-static mat. If you attempt to do this repair in the winter or at any time the relative humidity is lower than about 60%, a very real risk of ESD exists. If ESD occurs while holding either circuit board permanent damage to the controller electronics may occur. For reference, I conducted this repair in December with an indoor relative humidity of 45% and I noticed several ESD events while I was preparing the workspace. Don't think ESD won't happen to you, because by the time you notice it, the damage is already done.
Installation / Reassembly Procedure
- Top Cover Held on with 4 philips screws (2 top and 2 rear)
- Disconnect Cables next to cassette mechanism. First remove the black plastic push clips from cable. They pull upward. Then, unclip 2 cables from PCB's sockets.
- While screen is open / eject. Remove 4 screws from side of tilted screen. They are philips screws
- Pull out screen's facepanel and disassemble. The glass screen has (4) philips screws on the back, remove them, then separate the plastic front and rear.
- Remove the Philips Screws on back of PCB. There should be 6 brass color philips screws with washers to remove. GENTLY Unclip all wire harnesses attached to the PCB including the light sensor from the front faceplate. Be gentle because sometimes these can disintegrate and wires can fall out
- Remove 4 philips screws holding LCD onto metal backing Once these are removed, unclip the LCD's flat cable and power cable (white/yellow or orange).
- Remove the flat cable from old LCD and insert into replacement LCD You will need to unclip it and then make sure it is securely clipped into the replacement LCD.
- Reassemble Do everything previously stated in reverse.
