This display is in excellent working condition. We have successfully tested its functionality, including the SeaTalk port, card reader (no chart card included), radar port, SeaTalk HS port, and so on. Everything is fully functional! *All photos are of THIS display; some use peripherals that do not come with this listing (i.e. GPS antenna, radar, sounder module, transducer).* This unit is designated as an MME REFURB because it has gone through our rigorous testing procedure and had common failure points addressed. With our vast experience with pre-owned marine electronics, we can identify potential failures and have developed fixes for these failure points to ensure that our customers get the best-used unit out there. Within our extensive MME REFURBISHING process, we have installed a new LCD screen as well as rebuilt the backlight circuit with components superior to those originally found in this display. The unit was taken completely apart to restore the chassis/lightbox to white, eliminating the yellow hue around the edges often found on these displays, and then meticulously reassembled. The anti-glare coating of the lens has been removed and the lens has been polished to give a clean appearance. The operating system of this display has been updated to the latest software version, V5.69, to run at peak performance. There are signs of normal use, minor scratches, and blemishes, but this will not affect how this unit operates. Please see our photos for proof of functionality and more regarding the condition!
