In my 1200, the speaker is glued to the back and soldered into the board so there is no plug to undo. Just carefully find a position so that board doesn't pull on the speaker wire while it is open.

  • Unscrew the 2 screws on either side of the board.

For me, there were two screws, just located at the corners. One was near where the speaker is soldered to the board and the other was diagonally across the board where the GPS unit is soldered into the board.

  • Lift the circuit board up and disconnect the GPS connector.

My GPS unit, as mentioned, is soldered into the board, so no conector to remove. The GPS unit lifted right out with the board and was not attached to the display at all.

  • Peel back the tape securing the display connector to the logic board.

My Roadmate 1200 had no tape holding the ribbon cable. Instead, on the board is a thin stripe of black plastic which is the connector for the cable. You can catch your finger nail under the edge of the black plastic strip closest to where the ribbon enters the board. Gently lever it up and it pivots up and out of the way as it releases the ribbon cable. The cable then easily slide out. When you align and slide in the new cable, just gently push the strip back down and it will snap into place. Practice aligning the cable a few times with the old one, snapping it in place, before installing the new.

  • Remove the display connector from the device.
