Up for bid is a Raymarine ST290 Data Instrument Display. Listing includes only what is seen in photographs. As you can see I powered this up, and it goes through the menus, pages as you can se in the pictures. I don't have the rest of the system to test further. This was removed as part of a whole boat electronics upgrade. This unit was reported to be in working condition when removed, but because I have no way to test this and I never personally used it I have listed it in this category.  Please take a look at my other listings for more marine electronics, as well as lots of other marine gear and quality items. I'm always updating my inventory, so save me as a seller to keep up to date with my offerings. Good Luck, Happy Bidding!!!
