Abstract: The invention relates to an adjustable sunshade for shielding against sun, rain, snow, ice and other weather conditions. In particular, the adjustable sunshade includes a top panel pivotably coupled with side panels for moving between a folded position and an unfolded position. Further, the adjustable sunshade includes a flexible belt for securing to a perimeter of an electronics unit, such as marine electronics. Advantageously, the adjustable sunshade may be configured to accommodate electronic units of varying size and dimension to, for example, reduce the glare and provide protection from various weather and ambient conditions.
