The Dometic Passport IO display is designed for DX self-contained marine air conditioners and connects via an 8-pin cable—standard internet cables are not compatible. The display measures 3-7/8" x 4-1/2" with the bezel and 2-1/2" x 3-1/4" without it; the rear dimensions are 2-3/8" x 1.75". It mounts using self-adhesive tape—only peel two tapes initially to preserve the others for future use. This display is compatible solely with IO technology: if your current display shows a "P" when entering programming mode (activated by holding the power button while off), this unit will work; if it shows a "U," it will not. It replaces Dometic parts 222000245 and 340407. For a budget-friendly option, check for used displays under part #40-4004.
