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.
