Announcing a new panel-mounted navigator: the GPS 155XL TSO. This unit is IFR approach certified under TSO C129a A1 and offers a very high definition moving map. This development marries two of Garmin's product development strengths: crisp, high-detail moving map technology and Garmin's legacy of proven, approach-certified IFR GPS receivers.

The moving map on the GPS 155XL TSO is exceptionally sharp. The DSTN (double super twist nematic) LCD is the familiar yellow-on-black display that found success in the VFR-only GPS 150XL and GNC® 250XL. Individual pixels in these displays are transparent to the viewer, and SUAs actually appear as curved rings and alphanumeric characters are easily distinguishable.

The high-resolution display is readable from every angle in all lighting conditions. A photocell in the display automatically controls the intensity of the backlight and will reverse the display from black-on-yellow to yellow-on-black for maximum contrast in daylight or nighttime viewing. Users may also choose to make these adjustments manually according to their individual preferences.
