In most cases, a Disc Read Error is caused by the following:
• Disc was installed in the CD slot or other slot that is not for the map disc (see “Loading the Map Disc” below)
• Disc was installed upside-down (disc needs to properly be installed with the label side facing up)
• Disc may be scratched, dirty or wet (see nav manual on how to clean disc)
• Nav System or air temperature in vehicle may be excessively hot (allow vehicle to cool down)
• Rough road conditions may be causing the disc to read improperly while the vehicle is in motion (problem should go away on smoother roads)

Loading the Map Disc
By far the most common reason for a Disc Read Error is installing the disc in the CD slot, or another media slot that was not intended for the map DVD. To insure that you are properly loading the disc, please refer to the instruction provided in the Navigation manual. Instructions for each system are copied below for quick reference. It is important to follow the specific instruction for each system since nav systems vary in appearance and functionality (some map DVDs are inserted behind the screen, which must first be folded down, others have a visible dedicated DVD slot in the face while others have both a CD and DVD slot, and it is hard to tell the difference).
Important: Be sure to remove the old disc prior to trying to load the new one. Instructions for ejecting the disc are also in the nav manual.
