Garmin has provided Service Advisory 2051 for general recommendations, materials, and supplies to clean and disinfect Garmin products. Otherwise, not following the recommendations could void the warranty.

  • Cleaners containing ammonia will harm the anti-reflective coating on many Garmin aviation display lenses.
  • Disinfectant with a solution of 70% isopropyl alcohol that does not contain ammonia is preferred. Solutions of up to 91% isopropyl alcohol are also acceptable.
  • Clean the display lens using a clean lint-free cloth and a cleaner that is specified as safe for anti-reflective coatings.
  • For other exposed surfaces such as knobs, buttons, and bezels, a damp cloth with soap and water is acceptable.
  • Bleach-based cleaners, ammonia-based cleaners, or other harsh chemicals on any surface are not recommended.
  • Remove all soap/soap residue to prevent buttons and knobs from gumming up or becoming slippery.
  • Many aviation products are not rated as waterproof. Spraying or wetting the units to the extent where moisture could go beyond the exterior surfaces could damage the unit.

The glide path that is generated is based on the information that is used for the Localizer Performance with Vertical guidance (LPV) and Lateral Navigation / Vertical Navigation (LNAV/VNAV) procedures. It uses a specified decent angle that is centered at the MAWP (Missed Approach Waypoint) and at the TCH (Threshold Crossing Height). If this information is included in the electronic database for the approach, the 400W/500W series, G1000 with WAAS, and GTN-600/700 series will generate a glide slope.

This error message can result from a number of issues. Below is a list of the most common:

  • The SD card may be write protected. When write protected, data cannot be written to the SD  card. On the SD card there is a small locking mechanism that can slide up and down. To be unlocked, the locking tab should be closer to the metal contacts on the SD card. Furthermore, the process of inserting the SD  card into your Garmin device and/or SD card programmer may move the locking tab out of place.
  • The card programmer cannot read or write to a high capacity card. Some card programmers cannot handle high capacity SD cards without a software download or driver update.
  • There is an error or bad data region on the SD card. Perform an error checking scan of the card through Windows to correct the errors.
Newly Overhauled parts obtained from Garmin are designated with an N in their part number. This usually follows the 010- in the part number. As with most Garmin 010 part numbers, the N part numbers are for ordering purposes only and do not actually appear on the dataplate of the unit.

The GTN 650 is a replacement for the GNS-430W. You can compare the two units here
