Using a small flathead screwdriver, spread the cover at the bump. The ECU cover should then tilt up and come right off.<\/li>\n<li>With the plugs at the front, the left board is the NAV logic, and the right appears to be the AVC-LAN interface and power supply. There is a ribbon cable separating the two. These boards should lift right out, as the cover screws are holding them in place.<\/li>\n<li>At whichever location is easiest, lift the retaining clip at one end of the ribbon cable connecting the power supply board to the &#8220;logic&#8221; board, then gently pull the ribbon cable free. This effectively disconnects the battery backup from the ECU.<\/li>\n<li>I also spotted a black momentary switch on the power supply board. This may also be a reset\/backup power interrupt, however being a multi-layer board, I couldn&#8217;t easily follow the traces to double-check.
